Pin 1 (Offset Null): This pin is connected to an external potentiometer or resistor network. This is used to nullify the input offset voltage in the operational amplifier. It’s primarily used for fine adjustments to improve accuracy in sensitive applications.
Pin 2 (Inverting Input, V-): This is the inverting input pin of the op-amp. It is where the input signal is applied for inverted signal amplification. It works in conjunction with the non-inverting input (pin 3) to determine the gain and function of the amplifier.
Pin 3 (Non-Inverting Input, V+): The non-inverting input is used for applying the input signal in non-inverting mode. It is part of the differential input that determines the operational behavior and gain of the op-amp. The signal will appear at the output with the same phase (non-inverted).
Pin 4 (V-, Negative Power Supply): The negative supply voltage pin. The operational amplifier requires dual supply voltages, and this pin connects to the negative rail of the supply. In most cases, it would be ground or a negative voltage depending on the design.
Pin 5 (Output): The output of the operational amplifier. It provides the amplified version of the differential input voltage. It should be connected to the desired load or circuit where the amplified signal will be used.
Pin 6 (NC, No Connection): This pin is not internally connected to any circuit inside the device. It may be used for physical package routing and should be left unconnected in your design.
Pin 7 (V+, Positive Power Supply): This is the positive supply voltage pin. The operational amplifier requires a dual supply, and this pin connects to the positive supply rail. It ensures the proper operation of the op-amp within its required voltage range.
Pin 8 (Offset Null): Like Pin 1, this pin is used for offset adjustment. It provides an alternative connection for offset trimming.
