LM386 IC Amplifier

Hii friend,

Today I am going to make an audio amplifier.In this amplifier we will use LM386 IC.This IC amplifier sound is very good.

Let's get started

Components required -

(1.) Resistor - 1K x1

(2.) IC - LM386 x1

(3.) Speaker x1

(4.) aux cable x1

(5.) Battery with connector - 9V x1

(6.) Capacitor - 25V 10uf x1

(7.) Capacitor - 25V 220uf x2

(8.) 0-pcb x1

Cut pcb in the size of 1.5x1.5 inch.

Now connect all components with IC on pcb and solder it according to the circuit diagram.

after adding all components on the pcb it will look like the given picture.

Next Connect speaker to the pcb according to circuit diagram.

Now solder aux cable to the pcb according to circuit diagram.

Last step is to solder the battery wire to the circuit.

we can give 9V DC power supply to this circuit.

Now amplifier is ready to play.

Connect aux cable to the phone,laptop,tab,.......and play the songs.

Enjoy with full volume.

NOTE:If you want add a switch then add a switch between the wire of battery.

This type you can make LM386 IC to amplifier.

Thank you
