D313 audio amplifier circuit diagram.

The circuit shown below is not at all expensive as the amplifier contains only an op amp and four transistors easily available from your electronics junk box. Find below is the list of audio amplifier circuits. 2 x 60 watts stereo amplifier circuit is designed using lm4780 an audio amplifier ic that can deliver 60 watt rms output power per channel to 8 ohms speakers. In the buffer circuit coupled with op amp ic 4558 supplied 15vdc voltage circuit power supply you can see in the picture is flavored transistor d313 and b507.

12 watts transistor amplifier circuit description. A great sounding lm386 audio amplifier. Driver circuit using transistor mje340 mje350. Lm386 audio amplifier circuit with pcb it was my first mini audio amplifier.

Now that you ve seen the bare minimum of what it takes to make an audio amplifier with the lm386 lets build a higher fidelity version with an adjustable gain control. We have more related list of amplifier circuits that you may like to visit. And suitable for 9v battery. 2w 2w stereo using 3 lm386 here is an lm386 stereo audio amplifier circuit 2 watts.

Here the op amp used is ua 741 which produces the required gain. Audio equalizer tone control circuit with bass treble and mid frequency control using op amp tone control or active equalizer circuit especially bass treble and mid control based equalizer is an important circuit in. Advantages of using this ic are low harmonic distortion compared to other ic amplifiers of similar. Many people also use it.

Because it s easy to build and this ic always popular.
