MAX1393 1-Channel True-Differential/ 2-Channel Single-Ended

MAX1393 1-Channel True-Differential/ 2-Channel Single-Ended

The MAX1393/MAX1396 micropower, serial-output, 12bit, analog-to-digital converters (ADCs) operate with a single power supply from +1.5V to +3.6V. These ADCs feature automatic shutdown, fast wake-up, and a highspeed 3-wire interface. Power consumption is only 0.734mW (VDD = +1.5V) at the maximum conv.
