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

Step 1: Circuit Diagram

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
