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 LM386 Audio Amplifier Module is a mono audio amplifier based on the LM386 chip. … names and descriptions such as “LM386 Audio Amplifier Module 200 Times 5V–12V Input … This neat little ready-made module provides a gain of 200.
