Overview
The AD848JRZ is a high-speed, low-power monolithic operational amplifier produced by Analog Devices Inc. This device is part of the AD848 and AD849 family, known for their fast AC and good DC performance. The AD848JRZ is internally compensated, making it stable for closed-loop gains of 5 or greater. It utilizes Analog Devices' junction isolated complementary bipolar (CB) process, enabling high speed with low power consumption of 4.8 mA from the power supplies.
