The devices contain a 12-bit SAR ADC and a multiplexer to interface with a resistive touch-screen panel. A digital serial interface provides communications. The MAX11800–MAX11803 include digital preprocessing of the touch-screen measurements, reducing bus loading and application-processor resource requirements. The included smart interrupt function generator greatly reduces the frequency of interrupt servicing to the devices. The MAX11800–MAX11803 enter low-power modes automatically between conversions to save power, making the devices ideal for portable applications. The MAX11800/MAX11801 offer two modes of operation: direct and autonomous. Direct mode allows the application processor to control all touch-screen controller activity. Autonomous mode allows the MAX11800/MAX11801 to control touch-screen activity, thereby freeing the application processor to perform other functions. In autonomous mode, the devices periodically scan the touch screen for touch events without requiring host-processor intervention. This can be used to reduce system power consumption. An on-chip FIFO is used during autonomous mode to store results and increase effective data throughput and lower system power. The MAX11800–MAX11803 support data-tagging, which records the type of measurement performed; X, Y, Z1, or Z2, and the type of touch event; initial touch, continuing touch, or touch release. The MAX11800/MAX11802 support the SPI™ serial bus. The MAX11801/MAX11803 support the I²C serial bus. The MAX11800–MAX11803 are available in 12-pin TQFN and 12-pin WLP packages, and are specified over the -40°C to +85°C (extended) and -40°C to +105°C (automotive) temperature ranges. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5943 Mon, 9 Nov 2009 12:28:50 GMT MAX8831: High Efficiency White LED Step-Up Converter with I²C Interface in 2mm x 2mm WLP http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6007 The MAX8831 integrates a 60mA, 28V PWM DC-DC step-up converter with five low-dropout LED current regulators for display and keypad backlighting in cell phones, PDAs, and other portable devices. The IC provides up to 90% efficiency over the entire input voltage range of 2.7V to 5.5V. The step-up converter operates at a fixed 2MHz switching frequency, enabling the use of very small external components to achieve a compact circuit area. For improved efficiency, the step-up converter automatically transitions to pulse-skipping mode at light loads. Each of the five current regulators accommodates up to 9 series LEDs (depending on LED string forward voltage), and is independently programmed using an I²C interface. Two of the current regulators (LED1, LED2) are intended to support display backlight functions and are programmable up to 25mA using a 128-step logarithmic dimming scheme. The other three regulators (LED3, LED4, LED5) are suitable for keyboard backlight functions or for driving signal indicators, and are programmable up to 5mA using a 32-step logarithmic dimming scheme. The low-current regulators (LED3, LED4, LED5) can be operated from the step-up converter or from a separate low-voltage source. The I²C interface controls all operational aspects of the current regulators, including: on/off state, LED current, ramp-up/ramp-down timers, and blink rate timers (LED3, LED4, LED5). The MAX8831 write/read addresses are factory programmed at 0x9A/0x9B (contact the factory for other address options). The MAX8831 features open/short LED fault detection, output overvoltage protection, thermal shutdown, and open-circuit Schottky diode detection, with the status of each fault monitored continually for readback through the I²C interface. The MAX8831 is available in a tiny 2mm x 2mm, 16-bump WLP package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6007 Mon, 9 Nov 2009 12:28:50 GMT MAX9877AERP: Low RF Susceptibility, Mono Audio Subsystem with DirectDrive Headphone Amplifier http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6441 The MAX9877A combines a high-efficiency Class D audio power amplifier with a stereo Class AB capacitorless DirectDrive® headphone amplifier. Maxim's 3rd generation, filterless Class D amplifier with active emissions limiting* technology provides Class AB performance with Class D efficiency. The MAX9877A delivers up to 725mW from a 3.7V supply into an 8Ω load with 87% efficiency to extend battery life. The filterless modulation scheme combined with active emissions limiting circuitry and spread-spectrum modulation** greatly reduces EMI while eliminating the need for output filtering used in traditional Class D devices. The stereo Class AB headphone amplifier in the MAX9877A uses Maxim's patented DirectDrive architecture, that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, space, and component height. The device utilizes a user-defined input architecture, three preamplifier gain settings, an input mixer, volume control, comprehensive click-and-pop suppression, and I²C control. A bypass mode feature disables the integrated Class D amplifier and utilizes an internal DPST switch to allow an external amplifier to drive the speaker that is connected at the outputs of the MAX9877A. The MAX9877A is available in a thermally efficient, space-saving 20-bump MaxFilm package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6441 Mon, 9 Nov 2009 12:28:50 GMT MAX9259, MAX9260: Gigabit Multimedia Serial Link with Spread Spectrum and Full-Duplex Control Channel http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6098 The MAX9259/MAX9260 chipset presents Maxim's gigabit multimedia serial link (GMSL) technology. The MAX9259 serializer pairs with the MAX9260 deserializer to form a complete digital serial link for joint transmission of high-speed video, audio, and control data. The MAX9259/MAX9260 allow a maximum serial payload data rate of 2.5Gbps for a 15m shielded twisted-pair (STP) cable. The 24-bit or 32-bit width parallel interface operates up to a maximum bus clock of 104MHz or 78MHz, respectively. This serial link supports display panels from QVGA (320 x 240) up to XGA (1280 x 768), or dual-view WVGA (2 x 854 x 480). The 24-bit or 32-bit mode handles 21 or 29 bits of data, along with an I²S input, supporting 4- to 32-bit audio word lengths and an 8kHz to 192kHz sample rate. The embedded control channel forms a full-duplex, differential 100kbps to 1Mbps UART link between the serializer and deserializer. The host electronic control unit (ECU) or microcontroller (µC) resides either on the MAX9259 (for video display) or on the MAX9260 (for image sensing). In addition, the control channel enables ECU/µC control of peripherals in the remote side of the serial link through I²C (base mode) or a user-defined full-duplex UART format (bypass mode). The MAX9259 serializer driver preemphasis and channel equalizer on the MAX9260 extend the link length and enhance the link reliability. Spread spectrum is available on the MAX9259/MAX9260 to reduce EMI on the serial and parallel output data signals. The differential link complies with the ISO 10605 and IEC 61000-4-2 ESD-protection standards. The core supplies for the MAX9259/MAX9260 are 1.8V and 3.3V, respectively. Both devices use an I/O supply from 1.8V to 3.3V. The MAX9259/MAX9260 are available in a 64-pin TQFP package (10mm × 10mm) with an exposed pad. Electrical performance is guaranteed over the -40°C to +105°C automotive temperature range. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6098 Mon, 9 Nov 2009 12:28:50 GMT MAX8903A, MAX8903C, MAX8903D: 2A 1-Cell Li+ DC-DC Charger for USB* and Adapter Power http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6019 The MAX8903A/MAX8903C/MAX8903D are integrated 1-cell Li+ chargers and Smart Power Selectors™ with dual (AC adapter and USB) power inputs. The switch mode charger uses a high switching frequency to eliminate heat and allow tiny external components. It can operate with either separate inputs for USB and AC adapter power, or from a single input that accepts both. All power switches for charging and switching the load between battery and external power are included on-chip. No external MOSFETs, blocking diodes, or current-sense resistors are required. The MAX8903A/MAX8903C/MAX8903D feature optimized smart power control to make the best use of limited USB or adapter power. Battery charge current and SYS output current limit are independently set. Power not used by the system charges the battery. Charge current and SYS output current limit can be set up to 2A while USB input current can be set to 100mA or 500mA. Automatic input selection switches the system from battery to external power. The DC input operates from 4.15V to 16V with up to 20V protection, while the USB input has a range of 4.1V to 6.3V with up to 8V protection. The MAX8903A/MAX8903C/MAX8903D internally block current from the battery and system back to the DC and USB inputs when no input supply is present. Other features include prequal charging and timer, fast charge timer, overvoltage protection, charge status and fault outputs, power-OK monitors, and a battery thermistor monitor. In addition, on-chip thermal limiting reduces battery charge rate and AC adapter current to prevent charger overheating. The MAX8903A/MAX8903C/MAX8903D are available in a 4mm x 4mm, 28-pin thin QFN package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6019 Mon, 9 Nov 2009 12:28:50 GMT MAX2044: SiGe, High-Linearity, 2300MHz to 4000MHz Upconversion/Downconversion Mixer with LO Buffer http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5592 The MAX2044 single, high-linearity upconversion/downconversion mixer provides +32.5dBm input IP3, 8.5dB noise figure, and 7.7dB conversion loss for 2300MHz to 4000MHz LTE, WiMAX™, and MMDS wireless infrastructure applications. With an ultra-wide LO frequency range of 2600MHz to 4300MHz, the MAX2044 can be used in either low-side or high-side LO injection architectures for virtually all 2.5GHz and 3.5GHz applications. In addition to offering excellent linearity and noise performance, the MAX2044 also yields a high level of component integration. This device includes a double-balanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The MAX2044 requires a nominal LO drive of 0dBm, and supply current is typically 138mA at VCC = 5.0V or 121mA at VCC = 3.3V. The MAX2044 is pin similar with the MAX2029/MAX2031 650MHz to 1000MHz mixers and the MAX2039/MAX2041/MAX2042 1700MHz to 3000MHz mixers, making this entire family of up/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands. The MAX2044 is available in a compact 20-pin thin QFN (5mm x 5mm) package with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5592 Mon, 9 Nov 2009 12:28:50 GMT MAX9680: 3V Video Amplifier with Internal Gain and Filter in SC70 http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6355 The MAX9680 high-speed amplifier and filter is optimized for portable video applications. It is specifically designed to be compatible with the video encoders embedded in application processors with 0.4VP-P video output. The input common-mode range includes GND, which allows a video DAC (digital-to-analog converter) to be DC-coupled to the MAX9680. The output swings within 2mV of GND and 20mV to VDD with a standard back-terminated video load (150Ω). An internal level shift circuit prevents the output from saturating with 0V input, thus preventing sync-pulse clipping in common video circuits. Therefore, the MAX9680 is ideally suited for DC-coupling to the video load. The MAX9680 has been optimized for space-sensitive applications by integrating internal gain setting resistors (G = 5.2V/V) and a 2-pole video-DAC reconstruction filter. In shutdown mode, the quiescent current is reduced to less than 0.4µA, dramatically reducing power consumption and prolonging battery life. The MAX9680 is available in the tiny 2mm x 2.1mm, 6-pin, SC70 package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6355 Mon, 9 Nov 2009 12:28:50 GMT MAX17020: Dual Quick-PWM Step-Down Controller with Low-Power LDO, RTC Regulator http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6132 The MAX17020 is a dual Quick-PWM™ step-down power-supply (SMPS) controller with synchronous rectification, intended for main 5V/3.3V or I/O 1.5V/1.05V power generation in battery-powered systems. Lowside MOSFET sensing provides a simple low-cost, highly efficient current sense for valley current-limit protection. Combined with the output overvoltage and undervoltage protection features, this current limit ensures robust output supplies. The 5V/3.3V or 1.5V/1.05V SMPS outputs can save power by operating in pulse-skipping mode or in ultrasonic mode to avoid audible noise. Ultrasonic mode forces the controller to maintain switching frequencies greater than 20kHz at light loads. An internal 100mA linear regulator can be used to either generate the 5V bias needed for power-up or other lower power "always-on" suspend supplies. An independent bypass input allows automatic bypassing of the linear regulator when the SMPS is active. This main controller also includes a secondary feedback input that triggers an ultrasonic pulse (DL1 turned on) if the SECFB voltage drops below its threshold voltage. This refreshes an external charge pump driven by DL1 without overcharging the output voltage. The device includes independent shutdown controls to simplify power-up and power-down sequencing. To prevent current surges at startup, the internal voltage target is slowly ramped up from zero to the final target over a 1ms period. To prevent the output from ringing below ground in shutdown, the internal voltage target is ramped down from its previous value to zero over a 1ms period. Two independent power-good outputs simplify the interface with external controllers. The MAX17020 is a pin-for-pin replacement of the MAX8778. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6132 Mon, 9 Nov 2009 12:28:50 GMT MAX3543: Multiband Analog and Digital Television Tuner http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6430 The MAX3543 hybrid broadband single-conversion television tuner is designed for use in analog (PAL, SECAM) + digital (DVB-T, GB20600) television sets and terrestrial receivers. It receives all television bands from 47MHz to 862MHz and converts the selected channel to an industry-standard 36MHz IF. The MAX3543 includes a variable-gain low-noise input amplifier; an RF tracking filter; an image rejection mixer; a peak detector; an optional internal, self-contained RF gain-control loop (RFAGC); a VCO with fractional-N PLL; an IF bandpass filter; an IF variable-gain amplifier; separate analog and digital IF outputs; and a crystal oscillator. The MAX3543 is available in a small, 6mm x 6mm, thin QFN package, and the application circuit fits in 20mm x 25mm on a two-layer board with single-sided component mounting. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6430 Mon, 9 Nov 2009 12:28:50 GMT MAX9694: 14 Programmable Gamma Reference Buffers with Four Static References for TFT LCDs http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5954 The MAX9694 provides four static voltage references and 14 programmable voltage references for gamma correction in TFT LCDs. The MAX9694 also features a 7-bit digital variable resistor (DVR) for VCOM calibration in TFT LCDs. Gamma and DVR values are programmed into the registers through an I²C interface. The 14 programmable reference voltages are divided evenly into seven upper and seven lower voltages for the upper and lower gamma curves of LCD column drivers. Each channel has a static 8-bit digital-to-analog converter (DAC) and an isolation buffer to ensure stable reference voltages. This architecture reduces the effects of power-supply noise and kickback current from the source driver chips. Each buffer provides a high peak current to reduce the recovery time of the output voltages when critical levels and patterns are displayed. The MAX9694 has two features to protect the column drivers during startup. First, the gamma outputs remain in a high-impedance state until the registers are loaded. Second, the four reference buffers ramp up proportionally with the analog supply, which ensures that OUT_REFL_H is always at a lower voltage than OUT_REFU_L. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5954 Mon, 9 Nov 2009 12:28:50 GMT MAX8791: Single-Phase Synchronous MOSFET Driver http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6118 The MAX8791 is a single-phase synchronous noninverting MOSFET driver. The MAX8791 is intended to work with controller ICs like the MAX8736 or MAX8786, in multiphase notebook CPU core regulators. The regulators can either step down directly from the battery voltage to create the core voltage, or step down from the main system supply. The single-stage conversion method allows the highest possible efficiency, while the 2-stage conversion at higher switching frequency provides the minimum possible physical size. The low-side driver is optimized to drive 3nF capacitive loads with 4ns/8ns typical fall/rise times, and the high-side driver with 8ns/10ns typical fall/rise times. Adaptive dead-time control prevents shoot-through currents and maximizes converter efficiency. The MAX8791 is available in a small, lead-free, 8-pin 3mm x 3mm TQFN package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6118 Mon, 9 Nov 2009 12:28:50 GMT MAX17028, MAX17428: 1-Phase Quick-PWM Intel IMVP-6.5/GMCH Controllers http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6294 The MAX17028/MAX17428 are 1-phase Quick-PWMâ„¢ step-down VID power-supply controllers for Intel notebook CPUs. The Quick-PWM control provides instantaneous response to fast load current steps. Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors. The MAX17028/MAX17428 are intended for two different notebook CPU/GPU core applications: either bucking down the battery directly to create the core voltage, or else bucking down the +5V system supply. The single-stage conversion method allows these devices to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, 2-stage conversion (stepping down the +5V system supply instead of the battery) at higher switching frequency provides the minimum possible physical size. A slew-rate controller allows controlled transitions between VID codes. A thermistor-based temperature sensor provides programmable thermal protection. A current monitor provides an analog output current proportional to the processor load current. The MAX17028/MAX17428 implement both the Intel IMVP-6.5 CPU core specifications (V3P3 = 3.3V), as well as the Intel GMCH graphics core specifications (V3P3 = GND). The MAX17028/MAX17428 are available in a 32-pin, 5mm x 5mm, TQFN package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6294 Mon, 9 Nov 2009 12:28:50 GMT MAX19998: SiGe, High-Linearity, 2300MHz to 4000MHz Downconversion Mixer with LO Buffer http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5583 The MAX19998 single, high-linearity downconversion mixer provides 8.7dB of conversion gain, +24.3dBm input IP3, +11.3dBm 1dB input compression point, and a noise figure of 9.7dB for 2300MHz to 4000MHz WiMAX™, LTE, and MMDS receiver applications. With an ultra-wide LO 2600MHz to 4300MHz frequency range, the MAX19998 can be used in either low-side or high-side LO injection architectures for virtually all 2.5GHz and 3.5GHz applications. For a 2.5GHz variant tuned specifically for high-side injection, refer to the MAX19996A. In addition to offering excellent linearity and noise performance, the MAX19998 also yields a high level of component integration. This device includes a double-balanced passive mixer core, an IF amplifier, and an LO buffer. On-chip baluns are also integrated to allow for single-ended RF and LO inputs. The MAX19998 requires a nominal LO drive of 0dBm, and supply current is typically 230mA at VCC = 5.0V or 150mA at VCC = 3.3V. The MAX19998 is pin compatible with the MAX19996/MAX19996A 2000MHz to 3900MHz mixer family. The device is also pin similar with the MAX9984/MAX9986/MAX9986A 400MHz to 1000MHz mixers and the MAX9993/MAX9994/MAX9996 1700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a common PCB layout is used for multiple frequency bands. The MAX19998 is available in a compact, 5mm x 5mm, 20-pin thin QFN with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5583 Mon, 9 Nov 2009 12:28:50 GMT DS1080L: Spread-Spectrum Crystal Multiplier http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3436 The DS1080L is a low-jitter, crystal-based clock generator with an integrated phase-locked loop (PLL) to generate spread-spectrum clock outputs from 16MHz to 134MHz. The device is pin-programmable to select the clock multiplier rate as well as the dither magnitude. The DS1080L has a spread-spectrum disable mode and a power-down mode to conserve power. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3436 Mon, 9 Nov 2009 12:28:50 GMT MAX17021, MAX17082, MAX17482: Dual-Phase Quick-PWM Intel IMVP6+/6.5 CPU Controllers http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6131 The MAX17021/MAX17082/MAX17482 are 2/1-phase-interleaved Quick-PWM™ step-down VID power-supply controllers for notebook CPUs. True out-of-phase operation reduces input ripple current requirements and output- voltage ripple, while easing component selection and layout difficulties. The Quick-PWM control provides instantaneous response to fast load-current steps. Active voltage positioning reduces power dissipation and bulk output capacitance requirements and allows ideal positioning compensation for tantalum, polymer, or ceramic bulk output capacitors. A slew-rate controller allows controlled transitions between VID codes, controlled soft-start and shutdown, and controlled exit from suspend. A thermistor-based temperature sensor provides a programmable thermal-fault output (active-low VRHOT). A current monitor output (IMON) provides an analog current output proportional to the power consumed by the CPU (MAX17082/MAX17482 only). Output undervoltage, overvoltage (MAX17021/MAX17082 only), and thermal protection shut the controller down when any of these faults are detected. A voltage-regulator power-OK (PWRGD) output indicates the output is in regulation. Additionally, the MAX17021/MAX17082/MAX17482 feature true differential current sense and a phase-good (PHASEGD) output that indicates a phase imbalance fault condition. The MAX17021 supports the IMVP-6+ specification while the MAX17082/MAX17482 support the IMVP-6.5 requirements. The MAX17021/MAX17082/MAX17482 are available in a 5mm x 5mm, 40-pin TQFN package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6131 Mon, 9 Nov 2009 12:28:50 GMT
