The AD22057 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages (typically 100 mV FS at a gain of 40) from sources having a large common-mode voltage. Supply voltages from +3.0 V to +36 V can be used. The input common-mode range extends from below ground to +24 V.
The AD22057 is a single-supply difference amplifier designed for amplifying and low-pass filtering small differential voltages in the presence of large common-mode voltages. It features a gain of 320, an adjustable input common-mode range, and various low-pass filtering options. The device is suitable for applications such as current sensing, motor control, and interfacing with transducers like pressure sensors and strain gauges.
