ISL28194, ISL28195

Ultra-Small, 330nA and 1µA Single Supply,

Rail-to-Rail Input/Output (RRIO) Op Amps

The ISL28194 and ISL28195 are micropower op amps

optimized for low-power applications. The parts are

designed for single-supply operation from 1.8V to 5.5V,

making them suitable for applications with two 1.5V alkaline

batteries. The ISL28194 consumes typically 330nA of supply

current and the ISL28195 consumes typically 1µA of supply

current. Both parts feature rail-to-rail input and output swing

(RRIO), allowing for maximum battery usage.

Equipped with a shutdown pin, both parts draw typically 2nA

when off. The combination of small footprint, low power,

single supply, and rail-to-rail operation make them ideally

suited for all battery operated devices.
