GENERAL DESCRIPTION

The AD7823 is a high speed, low power, 8-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part contains a 4 μs typ successive approximation A/D converter, inherent track-and-hold functionality (with a pseudo differential input) and a high speed serial interface that interfaces to most microcontrollers. The AD7823 is fully specified over a temperature range of –40°C to +125°C.
