Overview
The AD823AARZ-RL, produced by Analog Devices Inc., is a dual precision operational amplifier (op amp) designed for high-performance applications. This JFET input op amp operates from a single supply of 3.0 V to 36 V or from dual supplies of ±1.5 V to ±18 V, making it highly versatile. The AD823AARZ-RL features a rail-to-rail bipolar output stage, which maximizes the output range and provides up to 40 mA of linear drive current. Its high impedance FET input stage ensures minimal loading of high output impedance devices, making it suitable for a wide range of signal processing tasks.
