Introduction: IRFZ44N Mosfet Amplifier
Today I am going to make an audio amplifier using MOSFET IRFZ44N.This amplifier circuit will give good sound.
Let's get started,
Step 1: Take All Components As Shown Below
Components required -
(1.) MOSFET - IRFZ44N x1
(2.) aux cable x1
(4.) Battery - 9V x1
(5.) Battery clipper x1
(6.) Capacitor - 16V 100uf
(7.) Resistor - 10K x1
Step 2: Mosfet IRFZ44N
This picture shows the output pins of this MOSFET.
Pin-1 - Gate
Pin-2 - Drain
Pin-3 - Source
Step 3: Solder 10K Resistor
Firstly we have to solder 10K resistor to Gate pin and Drain pin of the MOSFET as solder in the picture.
Step 4: Next Solder Capacitor
Next solder +ve pin of capacitor to the Gate pin of MOSFET as you can see in the picture.
Step 5: Next Connect Aux Cable Wire
Now we have to connect aux cable wire to the circuit.
Connect Left/Right (+ve) Wire of aux cable to -ve pin of capacitor and
Connect -ve (GND) wire of aux cable to Source pin of the MOSFET as you can see in the picture.
Step 6: Connect Speaker Wire
Now connect +ve wire of speaker to source pin of the MOSFET as solder in the picture.
Step 7: Connect Battery Wire
Next connect battery clipper wire to the circuit.
Solder +ve wire of battery clipper to the Drain pin of MOSFET and
-ve pin of battery clipper to -ve wire of speaker as you can see in the picture.
Step 8: Now Amplifier Circuit Is Ready
Now this MOSFET amplifier circuit is ready.
HOW TO USE IT -
Connect battery to the battery clipper and plug in aux cable to mobile phone/laptop/tab..... and play songs.
NOTE : If Amplifier is not working then change the polarity of battery.
Enjoy songs with full volume.
