Mosfet Audio Amp Circuit Diagram

2w 2w stereo using 3 lm386 here is an lm386 stereo audio amplifier circuit 2 watts.

Mosfet audio amp circuit diagram. 100w to 8 ohm speaker 160w to 4 ohm speaker low distortion. Hi fi 100w mosfet power amplifier circuit. Because of the voltage range and low noise productions. 2sc 5200 and 2sa 1943 is complementary transistors which are mostly using for power audio amplifier building.

2sc5200 amplifier circuit diagram. So the transistors are using in power audio amplifier circuits. These are npn and pnp power transistors. Use a 8 ohm 15w speaker as the load.

The first objective is to attain a considerable power gain that is sufficient to give a noise free audio signal at the output through speakers. The power transistors of the 400w amplifier circuit are bjt 2sc5200 2sa1943 or mosfet irfp240 irfp9240 can be used for this and will change materials for use. Go to top of list. Because it s easy to build and this ic always popular.

The gain stage uses a potential divider biased mosfet amplifier circuit. Mosfet audio amplifier circuit diagram 10 watts mosfet amplifier notes. 100w audio amplifier circuit diagram and explanation the schematic for this 100 watt audio amplifier has a few stages. And suitable for 9v battery.

The edited versions of the holy holton avxxx series amplifier circuits are of high quality pcb designs. The potential divider. At the beginning of the first stage amplification a filter section blocks unwanted frequency noises. Using 3 ics in a bridge model.

2sc 5200 transistor amplifier. Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v. Gain of the circuit. The circuit can be assembled on a vero board.

Supply voltage symmetrical 80v dc pcb schematic material list etc. Circuit topology is about the same of the above mentioned amplifier but the extremely rugged irfp240 and irfp9240 mosfet devices are used as the output. Lm386 audio amplifier circuit with pcb it was my first mini audio amplifier. Many people also use it.

50 watts mosfet amplifier. To celebrate the hundredth design posted to this website and to fulfil the requests of many correspondents wanting an amplifier more powerful than the 25w mosfet a 60 90w high quality power amplifier design is presented here. Do not expect much performance from this amplifier. This filter section is created using the r3 r4 and c1 c2.

How to make an audio amplifier using just one mosfet transistor an audio power amplifier or power amp is an electronic amplifier that strengthens low power inaudible electronic audio signals such as the signal from radio receiver or electric guit. To achieve this the following stages were employed in the amplifier. Audio amplifier circuit using mosfet transistor.
