Package

The LMC7221AIM5 is packaged in a 5-Pin SOT-23 configuration.

Pinout

The LMC7221AIM5 is a high-speed, single-supply, precision operational amplifier. It features a pin count of 8 pins. The functions of the pins are as follows:
1. Inverting Input (Pin 2): The input where the signal to be amplified is applied in an inverted manner.
2. Non-Inverting Input (Pin 3): The input for the signal to be amplified without inversion.
3. Output (Pin 6): The amplifier's output where the amplified signal is available.
4. Negative Supply Voltage (Pin 4): Typically connected to ground for single-supply operation.
5. Positive Supply Voltage (Pin 7): Connects to the positive power supply.
6. Offset Null (Pin 1): Used for adjusting the input offset voltage.
7. NC (Pin 5): No connection; this pin is not used.
8. Compensation (Pin 8): For frequency compensation, though often connected internally.
The LMC7221AIM5 is commonly used in precision signal processing applications due to its low offset voltage and high slew rate.
