Product Summary
The AD22057RZ 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 commonmode 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 using a +5 V supply with excellent rejection of this common-mode voltage. This is achieved by the use of a special resistive attenuator at the input, laser trimmed to a very high differential balance. The applications of the AD22057RZ include Current Sensing, Motor Control, Interface for Pressure Transducers, Position Indicators, Strain Gages, and Other Low Level Signal Sources Accelerometers.
