Pin Function Table (SOIC-8 Package) Pin Number Pin Name Pin Type Description 1 Output A Output Output of the first op-amp (A). 2 Inverting Input A Input Inverting input of the first op-amp (A). 3 Non-Inverting Input A Input Non-inverting input of the first op-amp (A). 4 V- (Negative Supply) Power Negative power supply (ground). 5 Non-Inverting Input B Input Non-inverting input of the second op-amp (B). 6 Inverting Input B Input Inverting input of the second op-amp (B). 7 Output B Output Output of the second op-amp (B). 8 V+ (Positive Supply) Power Positive power supply.Detailed Pin Function Descriptions:
Pin 1 - Output A: This is the output pin of the first operational amplifier (op-amp), labeled as A. The signal on this pin is the amplified version of the input signal, depending on the configuration of the external circuit (e.g., inverting, non-inverting).
Pin 2 - Inverting Input A: This pin is the inverting input of the first op-amp (A). It is connected to the inverting signal input from the external circuit. When the signal is applied to this pin, the output will be inverted relative to the input.
Pin 3 - Non-Inverting Input A: This is the non-inverting input of the first op-amp (A). A signal applied to this pin will produce a non-inverted output. The voltage gain of the op-amp depends on the resistor configuration between this input and the output.
Pin 4 - V- (Negative Supply): This pin is connected to the negative supply voltage (ground in most cases). It is required to complete the power circuit for the operational amplifiers within the IC.
Pin 5 - Non-Inverting Input B: This is the non-inverting input of the second operational amplifier (B). Like the non-inverting input of the first op-amp, the voltage gain is determined by the external components connected to this pin.
Pin 6 - Inverting Input B: This is the inverting input of the second operational amplifier (B). This input will invert the signal at the output of the second op-amp depending on the configuration.
Pin 7 - Output B: This pin provides the output of the second op-amp (B). The output is a result of the signal applied to the non-inverting or inverting inputs (depending on the circuit).
Pin 8 - V+ (Positive Supply): This pin is connected to the positive supply voltage. It is used to power the operational amplifiers inside the IC.
