Pin Number Pin Name Pin Function Description Pin 1 Output A This is the output of the first op-amp (Op-Amp A). It provides the amplified signal based on the input applied to the non-inverting or inverting terminal. Pin 2 Inverting Input A This is the inverting input for the first op-amp (Op-Amp A). This pin receives the input signal that will be inverted and amplified. Pin 3 Non-Inverting Input A This is the non-inverting input for the first op-amp (Op-Amp A). This pin receives the input signal that will be amplified in phase. Pin 4 Vss (Ground) This is the ground pin (0V reference) for the entire IC. It is connected to the system ground. Pin 5 Non-Inverting Input B This is the non-inverting input for the second op-amp (Op-Amp B). Similar to pin 3, this pin receives the input signal that will be amplified in phase. Pin 6 Inverting Input B This is the inverting input for the second op-amp (Op-Amp B). Similar to pin 2, this pin receives the input signal that will be inverted and amplified. Pin 7 Output B This is the output of the second op-amp (Op-Amp B). It provides the amplified signal for the second op-amp. Pin 8 Vcc ( Power Supply) This pin connects to the positive power supply voltage for the IC. Typically this is a voltage source between 3V and 32V, depending on the application.Circuit Principle:
The LM358 is a dual op-amp IC with two independent amplifiers in a single package. Each op-amp has its own input terminals and output terminal, as shown in the pinout. The operation of each op-amp is similar to that of standard op-amps. They work by amplifying the difference between the two input terminals and providing the output based on that amplified difference.
Basic Operation:
When the input signal is applied to the inverting or non-inverting terminal, the op-amp amplifies this difference. The output is provided on the respective output pin (Pin 1 for Op-Amp A and Pin 7 for Op-Amp B). The Vcc (Pin 8) and Vss (Pin 4) pins are used for powering the IC.FAQs for LM358DR2G :
