Description
The MAX11102/MAX11103/MAX11105/MAX11106/MAX11110/MAX11111/MAX11115/MAX11116/MAX11117 are 12-/10-/8-bit, compact, high-speed, low-power, successive approximation analog-to-digital converters (ADCs). These high-performance ADCs include a high-dynamic range sample-and-hold and a high-speed serial interface. These ADCs accept a full-scale input from 0V to the power supply or to the reference voltage.
The MAX11102/MAX11103/MAX11106/MAX11111 feature dual, single-ended analog inputs connected to the ADC core using a 2:1 MUX. The devices also include a separate supply input for data interface and a dedicated input for reference voltage. In contrast, the single-channel devices generate the reference voltage internally from the power supply.
These ADCs operate from a 2.2V to 3.6V supply and consume only 5.2mW at 3Msps and 3.7mW at 2Msps. The devices include full power-down mode and fast wake-up for optimal power management and a high-speed 3-wire serial interface. The 3-wire serial interface directly connects to SPI™, QSPI™, and MICROWIRE™ devices without external logic.
Excellent dynamic performance, low voltage, low power, ease of use, and small package size make these converters ideal for portable battery-powered data-acquisition applications, and for other applications that demand low-power consumption and minimal space.
These ADCs are available in a 10-pin TDFN package, 10-pin µMAX® package, and a 6-pin SOT23 package. These devices operate over the -40°C to +125°C temperature range.
