ADS1286

DESCRIPTION

The ADS1286 is a 12-bit, 20kHz analog-to-digital

converter with a differential input and sample and hold

amplifier and consumes only 250µA of supply cur-

rent. The ADS1286 offers an SPI and SSI compatible

serial interface for communications over a two or three

wire interface. The combination of a serial two wire

interface and micropower consumption makes the

ADS1286 ideal for remote applications and for those

requiring isolation.

The ADS1286 is available in a 8-pin plastic mini DIP

and a 8-lead SOIC.
