Pinout
The AD822ARMZ is an instrumentation amplifier manufactured by Analog Devices. It is typically housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pin functions are as follows:
1. Pin 1 (Ref): Reference voltage input. This pin allows for the output to be level-shifted. By default, it is usually connected to ground.
2. Pin 2 (V-): Negative power supply. This pin is connected to the negative voltage supply.
3. Pin 3 (RG2): Gain-setting resistor pin. Used in conjunction with RG1 to set the gain of the amplifier.
4. Pin 4 (IN-): Inverting input. It connects to the negative side of the differential input signal.
5. Pin 5 (IN+): Non-inverting input. It connects to the positive side of the differential input signal.
6. Pin 6 (RG1): Gain-setting resistor pin. Used in conjunction with RG2 to set the gain of the amplifier.
7. Pin 7 (V+): Positive power supply. This pin is connected to the positive voltage supply.
8. Pin 8 (Output): Output pin. This is where the amplified signal is available.
