Pin Function Specifications and Circuit Principles:
Here’s a detailed description of each pin's function for the LMC6482AIM (8-pin SOIC):
Pin Number Pin Name Function Description 1 Output A Output of the first op-amp in the dual configuration (output of the inverting amplifier). 2 Inverting Input A Inverting input of the first op-amp (the signal input for inverting configuration). 3 Non-Inverting Input A Non-inverting input of the first op-amp (used for non-inverting configuration). 4 V− (Negative Supply) Connects to the negative side of the power supply (ground for single-supply operation). 5 Non-Inverting Input B Non-inverting input of the second op-amp. 6 Inverting Input B Inverting input of the second op-amp. 7 Output B Output of the second op-amp. 8 V+ (Positive Supply) Connects to the positive side of the power supply.Pin Function Details:
Output A: This pin is the output of the first amplifier in the dual op-amp configuration. It provides the signal that has been amplified according to the configuration and external components.
Inverting Input A: The inverting input of the first op-amp is where the input signal is applied in an inverting amplifier configuration. It operates in conjunction with the non-inverting input and the feedback network.
Non-Inverting Input A: The non-inverting input of the first op-amp. The signal applied here results in a non-inverting amplifier configuration, which means the output is in phase with the input signal.
V− (Negative Supply): This pin connects to the negative side of the power supply. In a single-supply application, this would be ground.
Non-Inverting Input B: This is the non-inverting input for the second op-amp in the dual configuration. The signal applied here is amplified without inversion, depending on the external resistors in the feedback loop.
Inverting Input B: The inverting input for the second op-amp in the dual configuration. It works similarly to the inverting input of the first op-amp, but for the second op-amp.
Output B: This is the output pin for the second op-amp, similar to output A but for the second amplifier in the pair.
V+ (Positive Supply): This pin connects to the positive side of the power supply. For single-supply operation, this would be the positive voltage rail.
