Description

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.
