General Description
The MAX1392/MAX1395 micropower, serial-output, 10-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 0.740mW (VDD = +1.5V) at the maximum conversion rate of 357ksps. AutoShutdown™ between conversions reduces power consumption at slower throughput rates.
