GENERAL DESCRIPTION
The AD7810 is a high speed, low power, 10-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part contains a 2 µs successive approximation A/D converter, with inherent track/hold functionality, a pseudo differential input and a high speed serial interface that interfaces to most microcontrollers. The AD7810 is fully specified over a temperature range of –40°C to +105°C.
