Pinout

The LM386M-1 is a low-voltage audio power amplifier with a total of 8 pins. Here is the pin configuration and their functions:
1. Input (Pin 1): This is the non-inverting input for the audio signal.
2. Gain (Pin 2): This pin sets the gain of the amplifier. It can be connected to a resistor and capacitor to set a desired gain, typically 20 (26 dB).
3. Bypass (Pin 3): This pin is used to improve stability and reduce noise when a capacitor is placed between this pin and ground.
4. Power Supply (Pin 4): The positive power supply input, typically connected to a voltage between 4V and 12V.
5. Output (Pin 5): This pin delivers the amplified audio signal to the speaker or load.
6. Ground (Pin 6): The ground connection for the device.
7. Thermal (Pin 7): This pin provides thermal protection.
8. Power Supply (Pin 8): The negative power supply input, often connected to ground in single-supply applications.
The LM386M-1 is commonly used in portable audio applications due to its low power consumption and compact size.
