Overview
The AD8022ARM-REEL, produced by Analog Devices Inc., is a dual high-speed, low-noise voltage feedback operational amplifier. This component is designed for demanding applications requiring precision performance, particularly in environments where low voltage and current noise are critical. Each amplifier in the AD8022 consumes only 4.0 mA of quiescent current while maintaining a low voltage noise of 2.5 nV/√Hz at 100 kHz. The amplifiers are fabricated on Analog Devices’ proprietary eXtra-Fast Complementary Bipolar (XFCB) process, enabling high-frequency, low-distortion performance with low supply currents.
