AD22057RZ Datasheet PDF - ADI

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.

● Accurate midscale offset capability

● Transient spike protection and RFI filters included

● Indefinite output short-circuit duration

● Drives 1kR load to +4V using Vs=+5V

● 400kR Differential input resistance

● 60V Peak input voltage (40ms)

● -34V Reversed supply protection

●ESD sensitive device, electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
