On-board charge pumps convert the +5V input to the ±10V needed for RS-232 output levels. The MAX201 and MAX209 operate from +5V and +12V, respectively, and contain a +12V to -12V charge-pump voltage converter. The MAX200–MAX209/MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a 20kbps data rate. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification. The 5µW shutdown mode of the MAX200, MAX205, MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing the ring indicator (RI) to be monitored easily using only 75µW power. The MAX211 and MAX213 are available in a 28-pin, wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now available in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components and are recommended for applications with limited circuit board space. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1369 Tue, 24 Nov 2009 12:29:11 GMT MAX9918, MAX9919, MAX9920: -20V to +75V Input Range, Precision Uni-/Bidirectional, Current-Sense Amplifiers http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5846 The MAX9918/MAX9919/MAX9920 are single-supply, high-accuracy current-sense amplifiers with a high input common-mode range that extends from -20V to +75V. These amplifiers are well suited for current monitoring of inductive loads such as motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events. The MAX9918/MAX9920 feature adjustable gain set by an external resistive-divider network. The MAX9919 features fixed gains of 45V/V (MAX9919F) and 90V/V (MAX9919N). The MAX9918/MAX9919/MAX9920 operate as unidirectional amplifiers when VREFIN = GND and as bidirectional amplifiers when VREFIN = VCC/2. The MAX9920 attenuates the input signal by a factor of 4 at the input level-shifting stage allowing the device to sense voltages up to 200mV (unidirectional operation) or ±100mV (bidirectional operation). The MAX9918/MAX9919/MAX9920 operate with a single 5V supply voltage, are fully specified over the -40°C to +125°C automotive temperature range, and are available in an 8-pin SOIC package. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5846 Tue, 24 Nov 2009 12:29:11 GMT MAX2842: 3.3GHz to 3.9GHz MIMO Wireless Broadband RF Transceiver http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6443 The MAX2842 single-chip, direct-conversion, zero-IF RF transceiver IC is designed for 3GHz NLOS wireless broadband MIMO systems. It has two transmitters and two receivers, with differential 100Ω RF inputs and outputs. The IC includes all circuitry required to implement the complete RF transceiver function, providing fully integrated receive paths, transmit path, VCO and tank, frequency synthesis, and baseband/control interface. It includes a fast-settling sigma-delta RF fractional synthesizer with ~25Hz frequency step size. The IC also integrates an on-chip AM detector for measuring transmitter I/Q imbalance and LO leakage. An internal transmit-to-receive loopback mode allows for receiver I/Q imbalance calibration. The IC supports full duplex mode of operation for external loopback. The MAX2842 completely eliminates the need for external SAW filters by implementing on-chip programmable monolithic filters for both receiver and transmitter, for channel bandwidths from 3.5MHz to 10MHz. The baseband filtering Rx and Tx signal paths are optimized to meet stringent noise figure and linearity requirements. The transceiver is housed in a small 56-pin TQFN, 7mm x 7mm, leadless plastic package with exposed paddle. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6443 Tue, 24 Nov 2009 12:29:11 GMT MAX2852: 5GHz Receiver http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6459 The MAX2852 is a single-chip RF receiver IC designed for 5GHz wireless HDMI™ applications. The IC includes all circuitry required to implement the complete receiver function and crystal oscillator, providing a fully integrated transmit path, VCO, frequency synthesis, and baseband/control interface.

The receiver chip is housed in a small, 68-pin thin QFN leadless plastic package with exposed pad. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6459 Tue, 24 Nov 2009 12:29:11 GMT DS9107: iButton Capsule http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5190 The iButton® Capsule is a mechanical enclosure to protect Temperature Logger iButtons (DS1921 and DS1922 series) from moisture, solvents and pressure. It provides IP68 protection to the iButton inside (refer to Application Note 4126: Understanding the IP (Ingress Protection) Ratings of iButton Data Loggers and Capsule). The protection level exceeds the "Water Resistant 3 ATM" requirements. The DS9107 consists of a base with the cavity for a F5 iButton, a screw-in plug with O-ring to seal the enclosure, and a top with two stainless-steel screws to mount the iButton Capsule to a cable, e.g., to measure temperature at different levels within a liquid. The cable is inserted into the notch of the plug where it is held in place by the matching protrusion of the top piece. Base, plug, and top are made of polyphenylene sulfide (PPS). This material is chosen for its mechanical properties (remains stable during both long and short-term exposure to high temperatures), inherent flame resistance, and outstanding chemical resistance (inert to steam, strong bases, fuels and acids). Although PPS is virtually insoluble below 200°C, it can be attacked by chlorinated hydrocarbons. The silicone O-ring matches the temperature and chemical qualities of the PPS. In addition, it is resistant to sunlight, ozone, oxygen, and UV light. The chemical stability of the screws does not compromise that of the PPS and the silicone. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5190 Tue, 24 Nov 2009 12:29:11 GMT MAX5391, MAX5393: Dual 256-Tap, Volatile, Low-Voltage Linear Taper Digital Potentiometers http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6408 The MAX5391/MAX5393 dual 256-tap, volatile, low-voltage linear taper digital potentiometers offer three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +1.7V to +5.5V power supply, these devices provide a low 35ppm/°C end-to-end temperature coefficient. The devices feature an SPI™ interface. The small package size, low supply voltage, low supply current, and automotive temperature range of the MAX5391/MAX5393 make the devices uniquely suitable for the portable consumer market, battery backup industrial applications, and the automotive market. The MAX5391/MAX5393 include two digital potentiometers in a voltage-divider configuration. The MAX5391/MAX5393 are specified over the -40°C to +125°C automotive temperature range and are available in a 16-pin, 3mm x 3mm TQFN and a 14-pin TSSOP package, respectively. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6408 Tue, 24 Nov 2009 12:29:11 GMT DS1873: SFP+ Controller with Analog LDD Interface http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6281 The DS1873 controls and monitors all functions for SFF, SFP, and SFP+ modules including all SFF-8472 functionality. The DS1873 provides APC loop, modulation current control, and eye safety functionality. The DS1873 continuously monitors for high output current, high bias current, and low and high transmit power to ensure that laser shutdown for eye safety requirements are met without adding external components. Six ADC channels monitor VCC, temperature, and four external monitor inputs (MON1–MON4) that can be used to meet all monitoring requirements. MON3 is differential with support for common mode to VCC. Two digital-to-analog (DAC) outputs with temperature-indexed lookup tables (LUTs) are available for additional monitoring and control functionality. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6281 Tue, 24 Nov 2009 12:29:11 GMT MAX17122: Step-Up, Step-Down Regulator, Gate-On Charge Pump, and Boost-Buck Regulator for TV TFT LCD Display http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6413 The MAX17122 multiple-output power-supply IC generates all the supply rails for thin-film transistor (TFT) liquid-crystal display (LCD) TV panels. It can operate from 8V to 16.5V input voltages and is optimized for LCD TV panel applications running directly from 12V regulated supplies. It includes a 22V internal-switch step-down regulator for digital logic, a 22V internal switch step-up regulator to power the TFT source drivers, and a temperature-compensated 36V internal-switch boost-buck regulator that produces a negative output that can vary according to the temperature sensed by an external NTC thermistor. All three of these regulators feature high-efficiency and fixed-frequency operation. High-frequency operation allows the use of small inductors and capacitors, resulting in a compact solution. The MAX17122 includes a positive charge-pump linear regulator controller that uses an external pnp bipolar junction transistor (BJT) to typically form a regulated charge-pump doubler to supply the LCD positive gate-driver supply voltage. A negative gate-driver supply is derived linearly between the boost-buck regulator's output and ground, using an external npn BJT connected to ground and a small bypass capacitor. Other features include an external-capacitor-timed, open-drain, power-good output that monitors the step-down regulator's feedback and a simple untimed output that monitors the positive charge-pump linear regulator's feedback. A high-voltage stress function is available for the step-up regulator output. The GATE output directly drives an external p-channel MOSFET to provide True Shutdown™ of the step-up output. The MAX17122 is available in a 6mm x 6mm, 40-pin thin QFN package and operates over the -40°C to +85°C temperature range. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6413 Tue, 24 Nov 2009 12:29:11 GMT MAX6666, MAX6667: High-Accuracy PWM Output Temperature Sensors http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3065 The MAX6666/MAX6667 are high-accuracy, low-cost, low-power temperature sensors with a single-wire output. The MAX6666/MAX6667 convert the ambient temperature into a ratiometric PWM output with temperature information contained in the duty cycle of the output square wave. The MAX6666 has a push-pull output and the MAX6667 has an open-drain output. The MAX6666/MAX6667 operate at supply voltages from +3V to +5.5V. The typical unloaded supply current at 5.0V is 200µA. Both devices feature a single-wire output that minimizes the number of pins necessary to interface with a microprocessor (µP). The output is a square wave with a nominal frequency of 35Hz (±20%) at +25°C. The output format is decoded as follows: <blockquote> Temperature (°C) = 235 - (400 × t1)/t2 </blockquote> Where t1 is fixed with a typical value of 10ms and t2 is modulated by the temperature (Figure 1 in the full data sheet). The MAX6666/MAX6667 operate from -40° to +125° and are available in space-saving SOT23 packages. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3065 Tue, 24 Nov 2009 12:29:11 GMT MAX2135: ISDB-T/DVB-T Diversity Tuner http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6094 The MAX2135 low-power, 6MHz ISDB-T and 6MHz/7MHz/ 8MHz DVB-T low-IF diversity tuner directly converts broadcast ISDB-T and DVB-T signals to a low-IF using a broadband I/Q downconverter. The operating frequency range covers the VHF and UHF broadcast TV bands from 90MHz to 862MHz. The MAX2135 integrates LNAs, RF variable-gain amplifiers (VGAs), VHF and UHF tracking filters, I/Q downconverting mixers, baseband VGAs, and low-IF filters. The device also includes a fully monolithic VCO and tank circuit as well as a complete frequency synthesizer including an on-chip crystal oscillator and output buffer/divider. The device incorporates a 2-wire (I²C) serial control interface with multiple read and write addresses. A low-power standby mode is available whereupon the signal path is shut down while leaving the serial control interface and register circuits active. Additionally, the entire device can be shut down by an external pin. The MAX2135 is available in a 56-pin thin QFN package (7mm x 7mm) with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6094 Tue, 24 Nov 2009 12:29:11 GMT DS2482-101: Single-Channel 1-Wire® Master with Sleep Mode http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5953 The DS2482-101 is an I²C-to-1-Wire bridge device that interfaces directly to standard (100kHz max) or fast (400kHz max) I²C masters to perform bidirectional protocol conversion between the I²C master and any downstream 1-Wire slave devices. Relative to any attached 1-Wire slave device, the DS2482-101 is a 1-Wire master. Internal, factory-trimmed timers relieve the system host processor from generating time-critical 1-Wire waveforms, supporting both standard and overdrive 1-Wire communication speeds. To optimize 1-Wire waveform generation, the DS2482-101 performs slew-rate control on rising and falling 1-Wire edges and provides additional programmable features to match drive characteristics to the 1-Wire slave environment. Programmable, strong pullup features support 1-Wire power delivery to 1-Wire devices such as EEPROMs and sensors. The DS2482-101 combines these features with an output to control an external MOSFET for enhanced strong pullup application. The I²C slave address assignment is controlled by one binary address input, resolving potential conflicts with other I²C slave devices in the system. When not in use, the device can be put in sleep mode where power consumption is minimal. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5953 Tue, 24 Nov 2009 12:29:11 GMT MAX17121: Dual High-Voltage Scan Drivers for TFT LCD http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6330 The MAX17121 includes two high-voltage, level-shifting scan drivers for TFT panel integrated gate logic. Each scan driver has two channels that switch complementarily. The scan driver outputs swing from +40V to -30V and can swiftly drive capacitive loads. To save power, the scan driver's complementary outputs share the charge of their capacitive load before they change states. The MAX17121 is available in a 24-pin, 4mm x 4mm, thin QFN package with a maximum thickness of 0.8mm for ultra-thin LCD panels. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6330 Tue, 24 Nov 2009 12:29:11 GMT MAX15061: 80V, 300mW Boost Converter and Current Monitor for APD Bias Applications http://www.maxim-ic.com/quick_view2.cfm/qv_pk/6466 The MAX15061 consists of a constant-frequency pulse-width modulating (PWM) step-up DC-DC converter with an internal switch and a high-side current monitor with high-speed adjustable current limiting.
