AD22057RZ

AD22057 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages. The input common-mode range extends from below ground to +24V using a +5V 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. Typical applications include current sensing, motor control, interface for pressure transducers, position indicators, strain gauges and other low level signal sources and accelerometers.
