Overview

The ISL71444M features four radiation tolerant, low-power amplifiers optimized to provide maximum dynamic range. These op amps feature a unique combination of rail-to-rail operation on the input and output as well as a slew enhanced front-end that provides ultra fast slew rates positively proportional to a given step size. They also offer low-power, Low-offset voltage, and low temperature drift, making the ISL71444M ideal for applications requiring both high DC accuracy and AC performance.
