Pinout

The AD822BR is an instrumentation amplifier with a total of 8 pins. Here’s a brief overview of the pin functions:
1. Pin 1 (V+): Positive power supply input.
2. Pin 2 (V-): Negative power supply input.
3. Pin 3 (R_G): Gain resistor connection; used to set the gain of the amplifier.
4. Pin 4 (IN-): Negative input terminal for the differential signal.
5. Pin 5 (IN+): Positive input terminal for the differential signal.
6. Pin 6 (OUT): Output terminal; provides the amplified signal.
7. Pin 7 (NC): No connection; should be left unconnected.
