Detailed Explanation of Pin Functions

Pin 1 (IN-): Inverting input terminal of the op-amp. The input signal applied to this pin will be inverted at the output. Pin 2 (IN+): Non-inverting input terminal of the op-amp. The signal applied to this pin will appear at the output without inversion. Pin 3 (V-): Negative supply voltage pin. It provides the negative power for the op-amp. Pin 4 (V+): Positive supply voltage pin. It provides the positive power for the op-amp. Pin 5 (OUT): Output terminal where the amplified signal appears. Pins 6 to 24 (NC): No connection (internally not used). These pins do not have any functionality in the internal circuit of the device.
