General Description
The MAX11612–MAX11617 low-power, 12-bit, multi-channel analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. These devices operate from a single supply of 2.7V to 3.6V (MAX11613/MAX11615/MAX11617) or 4.5V to 5.5V (MAX11612/MAX11614/MAX11616) and require only 670µA at the maximum sampling rate of 94.4ksps. Supply current falls below 230µA for sampling rates under 46ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates. The MAX11612/MAX11613 have 4 analog input channels each, the MAX11614/MAX11615 have 8 analog input channels each, while the MAX11616/MAX11617 have 12 analog input channels each. The fully differential analog inputs are software configurable for unipolar or bipolar, and single-ended or differential operation.
