The AD620AR is an instrumentation amplifier with an 8-pin configuration. Here’s a brief overview of its pin functions:
1. Pin 1 (Ref): Reference terminal. A voltage applied here shifts the output voltage by the same amount. Typically connected to ground for differential measurements.
2. Pin 2 (-IN): Inverting input. Connects to the negative side of the input voltage.
3. Pin 3 (+IN): Non-inverting input. Connects to the positive side of the input voltage.
4. Pin 4 (-V): Negative power supply. Provides the negative supply voltage.
5. Pin 5 (RG): Gain resistor pin. Gain is set by connecting a resistor between pins 1 and 8. If left open, the gain defaults to 1.
6. Pin 6 (Output): Output terminal. Provides the amplified output signal.
7. Pin 7 (+V): Positive power supply. Provides the positive supply voltage.
8. Pin 8 (RG): Gain resistor pin. Works with Pin 5 to set the gain via an external resistor.
