19-5225; Rev 0; 4/10 www.DataSheet4U.com KIT ATION EVALU E L B AVAILA 2.7V to 3.6V and 4.5V to 5.5V, Low-Power, 1-/2-Channel, 2-Wire Serial, 12-Bit ADCs General Description The MAX11644/MAX11645 low-power, 12-bit, 1-/2channel 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 (MAX11645) or 4.5V to 5.5V (MAX11644) and require only 670µA at the maximum sampling rate of 94.4ksps. Supply current falls below 230µA for sampling rates under 40ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates.
