General Description

The MAX1393/MAX1396 micropower, serial-output, 12-bit, 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 high-speed 3-wire interface. Power consumption is only 0.734mW (VDD = +1.5V) at the maximum conversion rate of 312.5ksps. AutoShutdown? between conversions reduces power consumption at slower throughput rates.
