Rochester Electronics Interface - Sensor and Detector Interfaces AD22057R

The AD22057R is a single-supply difference amplifier designed for amplifying and low-pass filtering small differential voltages, particularly in applications with large common-mode voltages. It operates with supply voltages ranging from +3.0 V to +36 V and features a gain that can be adjusted from 31 to 3160, with a default gain of approximately 20. The input common-mode range extends from below ground to +24 V, making it suitable for various sensor applications. This amplifier includes transient spike protection and RFI filters, ensuring reliable performance in noisy environments. It can drive a 1 kOc load to +4 V using a +5 V supply and has an operating temperature range of -40¬8C to +125¬8C. The device is packaged in an 8-lead SOIC format, making it compact for integration into various designs. The AD22057R is particularly useful for current sensing, motor control, and interfacing with pressure transducers and strain gauges.
