AD626 is a low-cost, single-supply differential amplifier designed to amplify and low-pass filter small differential voltages from sources having a large common-mode voltage.
The AD626 is a low cost, true single supply differential amplifier designed for amplifying small differential voltages from sources having a large common-mode voltage. It operates from either a single supply of +2.4 V to +10 V or dual supplies of 1.2 V to ±6 V.
Key features include pin selectable gains of 10 and 100, input protection against continuous overload up to 50 V, and included RFI filters. The device is available in two 8-lead packages: a plastic mini-DIP and SOIC.
| Input Offset Voltage Max | 500 uV |
|---|---|
| Common-Mode Rejection Ratio Typ | 90 dB |
| Settling Time to 0.01% | 24 us |
| Operating Temperature Range | -40°C to +85°C |
