LM386 Ic Audio Amplifier

This is how you can make audio amplifier using LM368 ic

Supplies

list of components :) -

1)LM386 ic × 1

2)1000uf capacitor × 1

3)100uf capacitor × 2

4)0.1uf ceramic capacitor (cap num)104 × 1

5)Male audio jack mono plug/dual plug × 1

6)speaker

7)jumper wires

8)1k resister × 1

Step 1: Power Rails

were using these as power rails

you can give the circuit

5-12 v of power

Step 2: IC Pinout

attach LM386 ic on the breadboard

Step 3: Power Ic

join pin 4 of ic to the negative rail and pin 6 of ic to positive

Step 4: Add 0.01uf Capacitor

connect 0.1uf ceramic capacitor (cap num 104)

to pin 5 of the ic and pin of

ceramic capacitor to ground

and also connect pin 2 of ic to ground

Step 5: Connecting Speaker

connect 1000uf capacitor anode to pin 5 of ic

and cathode pin of the capacitor to pin1 of the speaker

and pin 2 of the speaker to ground

Step 6: Connecting Audio Jack

connect 1k resistor to pin 3 of ic and the second leg of

resistor to an empty row of the breadboard

now connect the audio jack to the ground pin of the jack

to ground and data pin of the jack to the second leg of the resistor

Step 7: Bypass Pin

connect one 100uf capacitor anode to pin 7

of ic and cathode pin of the capacitor to ground

Step 8: Noise Remove

(if you're using a battery skip it)if you are using a power

supply, adopter, and power from the use of cable

do this step connect the 100uf capacitor anode to the positive power rail

and cathode pin to ground

Step 9: Ready to Use

now you can connect the jack to the mobile, computer, or any audio devices
