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, 20 kHz analog‑to‑digital converter with a serial SPI/SSI interface and ultra‑low supply current, making it suitable for remote and battery‑operated data‑acquisition applications. It offers guaranteed no‑missing‑code operation, differential inputs, and a variety of package options.
The datasheet lists detailed electrical specifications, absolute maximum ratings, pin configurations, typical performance curves, timing diagrams, and package ordering information. It also includes a notice from Texas Instruments regarding product updates and usage restrictions.
