General Description
The MAX1136–MAX1139 low-power, 10-bit, multichannel 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.

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 MAX1136/MAX1137 have four analog input channels each, while the MAX1138/MAX1139 have 12 analog input channels each.
The fully differential analog inputs are software configurable for unipolar or bipolar, and single ended or differential operation.
The full-scale analog input rang...
