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 design of LM386 Audio Amplifier Circuit is very simple. First, connect the power supply pins (Pins 6 and 4) to 12V and Ground respectively. Note that the maximum power supply for LM386 is 15V. Next, we need to connect the input. The input can be given from any audio source like mobile phone or a microphone.

This LM386 audio amplifier circuit can be also used to record any sound. We just need a 3.5 mm audio plug and a computer with sound recording software. We only need to connect computer’s 3.5mm jack in place of Speaker, using 3.5mm audio plug, and we can easily record our voice or any sound into computer like a professional microphone.

The LM386 is an integrated circuit featuring a low-voltage audio power amplifier. It delivers low-level voltage amplification for consumer applications. In that case, the gain sets to 20 without external components. But connecting a capacitor and resistor between pins 1 and 8 increases the gain’s value between 20 and 200.
