This LM386 based audio amplifier is built around the amplifier LM386, an 8-ohm, one-watt speaker (LS1), four capacitors and other components.
The LM386 chip is a simple and cheap amplifier chip that is used in countless audio amplifier projects. I used one to make my own 0.5W amplifier. This is not a complete how-to guide, you can find plenty of those elsewhere. It’s just a write-up of some of the things I learned – and modifications…

This project shows how to build an Audio amplifier based on LM386 IC. The circuit is very simple and construction is easy on a breadboard. The LM386 IC is unique in that the gain can be modified by changing Resistor R2 and Capacitor C2. This configuration will give us a gain of 20. By removing R2 and connecting C2 across pins 1 and 8, we can increase the gain to 200. It is important to understand that increasing the gain does not increase the output power. The increased gain is only used when a very low input signal is to be amplified. In a previous article I discussed building audio amplifiers using discrete transistors. While it is possible to build good audio amplifiers from discrete transistors, they are no match for the many audio amp IC's available to us. IC's offer many advantages including high efficiency, high gain, low standby current, low component count, small size and ,of course, low cost. It is little wonder that audio amp IC's have replaced discrete transistors in most consumer electronic devices. While many experimenters have stayed away from these little black mysteries, I am going to uncover some of their secrets and demonstrate how easy they are to use.
