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.
The ADS1286 is a 12‑bit, 20 kHz analog‑to‑digital converter designed for remote and battery‑operated applications. It features a differential input, sample‑and‑hold amplifier, and both SPI and SSI compatible serial interfaces, enabling simple two‑ or three‑wire communication while consuming only 250 µA of supply current.
The datasheet provides full electrical specifications, pin assignments, package options, typical performance curves, and timing diagrams. It also includes absolute maximum ratings, ordering information for the 8‑pin PDIP and SOIC packages, and TI’s product status and compliance notes.
