ADI AD22057RZ

传感器接口电压模拟

Overview

The AD22057RZ is a single-supply Difference Amplifier for amplifying and low-pass filtering small differential voltages from sources having a large common-mode voltage. Supply voltages from +3 to +36V can be used. 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. Provisions are included for optional low-pass filtering and gain adjustment. An accurate midscale offset feature allows bipolar signals to be amplified.
