The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.

The detailed LM386 pin configuration is. LM386 Audio Amplifier Circuit Diagram and Working. In the circuit diagram of LM386, when the gain setting pins are open, then the gain will be 20 and it is set up by 1.35kW internal resistances, Or else in between the gain setting pins when a capacitor is placed, this bypasses the internal resistances and the gain reaches to 200.
