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
Power Rails
were using these as power rails
you can give the circuit
5-12 v of power
IC Pinout
attach LM386 ic on the breadboard
Power Ic
join pin 4 of ic to the negative rail and pin 6 of ic to positive
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
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
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
Bypass Pin
connect one 100uf capacitor anode to pin 7
of ic and cathode pin of the capacitor to ground
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
Ready to Use
now you can connect the jack to the mobile, computer, or any audio devices
