The LM321 is a single operational amplifier with a 5-pin configuration typically used in various electronic applications. Here is a concise breakdown of its pin count and functions:
1. Pin 1 (Offset Null): This pin is used for offset voltage adjustment. By connecting a potentiometer between Pins 1 and 5, you can nullify any offset voltage.
2. Pin 2 (Inverting Input): This is the inverting input terminal of the operational amplifier. A voltage applied to this pin will be amplified and inverted at the output.
3. Pin 3 (Non-inverting Input): This is the non-inverting input terminal. A voltage applied to this pin will be amplified and appear in-phase at the output.
4. Pin 4 (V- or Ground): This pin is connected to the negative supply voltage or ground in a single-supply application.
5. Pin 5 (Output): The amplified signal is output from this pin.
Note: Some package types might include additional or fewer pins, but the above describes a typical configuration for LM321 in its common package forms, like the 5-pin SOT-23.
