The AD623AR is an instrumentation amplifier available in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here's a concise overview of its pin configuration and functions:
1. Pin 1 (Ref): This is the reference pin. It allows the output voltage to be shifted by applying a voltage at this pin. If left unconnected, it is typically grounded.
2. Pin 2 (–IN): Inverting input. This is one of the differential inputs to the amplifier.
3. Pin 3 (+IN): Non-inverting input. This is the other differential input to the amplifier.
4. Pin 4 (–Vs): Negative supply voltage. Connect to the lower end of the supply range.
5. Pin 5 (Rg): Gain setting resistor. Connecting a resistor between Pin 5 and Pin 8 sets the gain of the amplifier according to the formula \( G = 1 + (100 kΩ/Rg) \).
6. Pin 6 (Vout): Output voltage. This is where the amplified signal is output.
7. Pin 7 (+Vs): Positive supply voltage. Connect to the higher end of the supply range.
8. Pin 8 (Rg): This pin is also part of the gain setting function, connected externally to Pin 5 via a resistor to set gain.
This pin configuration supports the AD623AR's function as a low-cost, high-precision instrumentation amplifier with adjustable gain.
