Audio Amplifier Circuit using OP-AMP LM386

This post is about an audio amplifier circuit. Here an Op-Amp is used to amplify the audio signal. The main equipment of this circuit is LM386, a non inverting Op-Amp.

The mechanism of this circuit is very easy to understand. It's very low in cost. Lets see how to work with this..
At first you have to buy all of the equipments listed below,

Parts List:

1. Op-Amp  LM386;
2. C1,C2,C4= 100nF, ceramic disc capacitor;
3. C3= 10uF Electrolyte Capacitor of 25V;
4. C5= 330uF Electrolyte Capacitor of 25V;
5. RV1= 100k ohms Variable Resistor;
6. R1= 10 ohms Resistor;
7. Speaker of 10 ohms;
8. 9V or 12V DC regulated power supply(max. 16V).

After having all the equipments, connect the circuit according to the schematic given below,

Re-check the circuit again. Connect the circuit with 9V or 12V DC Power and give an audio signal at the audio in section. You will hear the signal through speaker louder. 

* Set a plastic knob with the wiper of the potentiometer. 

*Check all the ground properly.

Thanks!
