General Description
The MAX11646/MAX11647 low-power, 10-bit, 1-/2-channel analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, a clock, and an I2C-compatible 2-wire serial interface. These devices operate from a single supply of 2.7V to 3.6V (MAX11647) or 4.5V to 5.5V (MAX11646) and require only 670µA at the maximum sampling rate of 94.4ksps.
