MAX1239EEE+

The MAX1239 low-power, 12-bit, multichannel analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, clock, and an I 2C-compatible 2-wire serial interface. These devices operate from a single supply of 2.7V to 3.6V 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.
