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.
The ADS1286 is a 12-bit analog-to-digital converter featuring a differential input, sample and hold amplifier, and a serial interface compatible with SPI and SSI. It is designed for low power consumption, drawing only 250 µA of supply current, making it ideal for battery-operated systems and remote data acquisition.
