Pinout
Here is a brief overview of the pin functions:
1. Pin 1 - Offset Null: Used for offset voltage adjustment.
2. Pin 2 - Inverting Input (IN-): Receives the input voltage signal that is inverted at the output.
3. Pin 3 - Non-Inverting Input (IN+): Receives the input voltage signal that is amplified without inversion.
4. Pin 4 - V- (Negative Power Supply): Connects to the negative power supply voltage.
5. Pin 5 - Offset Null: Used for offset voltage adjustment.
6. Pin 6 - Output: The amplified output signal is available on this pin.
7. Pin 7 - V+ (Positive Power Supply): Connects to the positive power supply voltage.
8. Pin 8 - No Connect (NC): Typically not internally connected and often unused.
This operational amplifier is typically used in applications requiring low power and single-supply operation.
