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:
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
