D313 Audio Amplifier Circuit Diagram

Lm386 audio amplifier circuit with pcb it was my first mini audio amplifier.

D313 audio amplifier circuit diagram. 12 watts transistor amplifier circuit description. Many people also use it. The four transistors are wired as complementary darlington s which produces the drive for the speaker. And suitable for 9v battery.

Because it s easy to build and this ic always popular. Using 3 ics in a bridge model. Most of the component values in this circuit aren t critical. Here the op amp used is ua 741 which produces the required gain.

For use transformer it s using one transformer by one circuit mono. 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. 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. 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.

Driver circuit using transistor mje340 mje350. 2w 2w stereo using 3 lm386 here is an lm386 stereo audio amplifier circuit 2 watts. 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.
