12v Mosfet Amplifier Circuit Diagram. Testing the class d amplifier circuit. Use a 8 ohm 15w speaker as the load.
Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal. Depending on this gate voltage we can change the conductivity and thus we can use it as a switch or as an amplifier like we use transistor as a switch or as an amplifier. 50w bcl car audio using tda1562.

Mosfet stands for metal oxide field effect transistor which has a gate. Testing the class d amplifier circuit. As i am using an affordable chinese one it gives off a little more than the 12v it s 13 5v to be exact which is perfect for our onboard lm7812 voltage regulator. All used in a car or in a house with a 12v dc power supply.
