Overview
The AD8022ARM is a high-performance, dual-channel operational amplifier designed and manufactured by Analog Devices Inc. This voltage-feedback op amp is particularly suited for applications requiring low voltage and current noise, such as ADSL (Asymmetric Digital Subscriber Line) and other xDSL (Digital Subscriber Line) systems. The AD8022ARM is fabricated on Analog Devices’ proprietary eXtra-Fast Complementary Bipolar (XFCB) process, which enables high-frequency, low-distortion performance with low supply currents.
