Overview
The AD8022AR-REEL7, produced by Analog Devices Inc., is a dual high-speed, low-noise voltage feedback operational amplifier. This component is designed for applications requiring low voltage and current noise, low supply current, and low distortion. The AD8022 is fabricated on Analog Devices’ proprietary eXtra-Fast Complementary Bipolar (XFCB) process, which enables the construction of high-frequency, low-distortion amplifiers. Each amplifier in the AD8022 consumes only 4.0 mA of quiescent current while offering a voltage noise of 2.5 nV/√Hz. The device is available in both 8-lead MSOP and 8-lead SOIC packages, making it versatile for various design needs.
