How To Make An Lm386 Audio Amplifier Circuit

By | July 18, 2023



Making an LM386 audio amplifier circuit is a great way to boost the sound from your audio device. It’s an easy and inexpensive project that can be completed in just a few steps.

The first step is to gather the necessary components. You will need an LM386 amplifier IC, a 10uf capacitor, a 0.1uf capacitor, a 100k ohm resistor, and two speakers. Once these components are in hand, you can begin wiring them up.

Start by connecting the 10uf capacitor between pins 1 and 8 of the LM386 IC. Then connect the 0.1uf capacitor between pin 5 and the ground. Next, connect the 100k ohm resistor between pins 1 and 5 of the IC. Finally, connect the two speakers to pins 7 and 8 of the IC. When the connections are complete, power the circuit with a 9V battery and you should hear the amplified sound coming from the speakers.

Making an LM386 audio amplifier circuit is a simple and cost-effective way to increase the volume of your audio devices. All it takes is a few components, some basic wiring, and a 9V battery. With just a little bit of effort, you can have an amplified system that is ready to go.
