Simple DIY Audio Amplifier Lm386

In this instructable, we are going to make a simple audio amplifier using lm386. LM386 is low voltage audio amplifier and gain range from 20 to 200. It's a 8-pin ic.

List of components:

1. Breadboard

2. LM386

3. 8 Ω speaker

4. 10k pot

5. 220 uF capacitor

6. 9-volt battery with snip connector

7. Connecting wires

In this circuit our gain is limited to 20 (26 dB). The 10k pot is used for adjusting the volume.

The circuit is self-explanatory
