Pin Descriptions: Pin 1 (VP): Supply Voltage Positive (Power Supply Pin) Connect the positive terminal of the power supply (3V to 6V) here. Pin 2 (IN+): Non-Inverting Input This is the input pin for the audio signal. The signal is applied here for amplification. Pin 3 (GND1): Ground This is the ground pin for the input section of the IC. It connects to the system ground. Pin 4 (VC): Volume Control (optional) This pin can be used for volume control. In some designs, it is connected to an external potentiometer or other volume adjustment circuitry. Pin 5 (OUT+): Positive Output This is one of the audio output pins. It connects to the positive terminal of the speaker. Pin 6 (GND2): Ground This is the ground pin for the output section. It should be connected to the system ground. Pin 7 (NC): No Connection This pin is not connected internally. It can be left unconnected in the circuit. Pin 8 (OUT-): Negative Output This is the second output pin, connecting to the negative terminal of the speaker. How the Pins Relate to the Circuit:
