ISL28194

Ultra-Small, 330nA and 1µA Single Supply, Rail-to-Rail Input/Output (RRIO) Op Amps

Product Status: Mass Production

OVERVIEW

The ISL28194 is micropower op amps optimized for low-power applications. The part is designed for single-supply operation from 1.8V to 5.5V, making it suitable for applications with two 1.5V alkaline batteries. The ISL28194 consumes typically 330nA of supply current . The part feature rail-to-rail input and output swing (RRIO), allowing for maximum battery usage.

Equipped with a shutdown pin, the part draw typically 2nA when off. The combination of small footprint, low power, single supply, and rail-to-rail operation makes it ideally suited for all battery operated device.
