The AD22057 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 common-mode voltage.
The AD22057 is a single-supply difference amplifier designed to amplify small differential voltages from sources with large common-mode voltage. It includes features such as an alterable gain ranging from x1 to x160, input common-mode rejection ratio (CMRR) up to 90 dB, and built-in low-pass filtering options.
| Gain Range | x1 to x160 |
|---|---|
| Supply Voltage | +3.0 V to +36 V |
| Operating Temperature Range | -40°C to +125°C |
| Input CMR Positive | +24 V |
| Bandwidth | 20 kHz (Typ) |
The overall default gain is x20.
Yes, it is an ESD sensitive device and proper precautions are recommended.
