12-Bit Micro-Power Sampling Analog-to-Digital Converter (ADC)

12-Bit Micro-Power Sampling Analog-to-Digital Converter (ADC) - ADS1286
Datasheet
 

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 current. 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.
