AD22050RZ-REEL7

Overview

The AD22050RZ-REEL7 is a single-supply difference amplifier manufactured by Analog Devices Inc. in an SOIC-8 package. It amplifies small differential voltages from sources with large common-mode voltages, featuring a default gain of 20 alterable from 31 to 3160. The input common-mode range extends from below ground to 6 times (VS – 1 V). Operating on supply voltages from +3.0 V to +36 V, it includes transient spike protection and RFI filters. The device supports 1-, 2-, or 3-pole low-pass filtering and offers accurate midscale offset capability for bipolar signals.
