Single Supply Sensor Interface Amplifier

Product Details

The AD22057 is a single-supply difference amplifier for the amplification and low-pass filtering of small differential voltages from sources having a large common-mode voltage.

Supply voltages from +3 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 range is achieved by the use of a special resitive attenuator at the input, laser trimmed to a very high differential balance. Low initial offset voltage and offset voltage drift are specified, and long-term stability of gain and offset voltage is also provided.

Provisions are included for optional low-pass filtering and gain adjustment. An accurate midscale offset feature allows bipolar signals to be amplified.
