Many electronics circuits and projects for learning in simple ways.

TBA820M Amplifier circuit stereo 2 watts

This is TBA820m Amplifier circuit stereo 2W+2W, supply voltage 12V, Easy to build and cheap.
If you want mini amplifier circuit , as a result do not be defeated certainly. The sound will a little 2W+2W just but enough with 6 sizes are inch 8ohm loudspeakers. as a result still have a voice good loud the moderately. Request friends have fun the circuit amplifies this miniature please yes.

If phone your light exceedingly ring. Invite come to this way. I thinks this circuit can help. It is Telephone Amplifier circuit. By have pillar equipment be IC LF351 perform enlarge telephone signal from pick up give the power goes up. Before transmit to IC TBA820M for amplify with a loudspeaker next sir. And VR1 perform fine the loud sound or the silent
is extremely fond of something. See circuit detail enhances in a picture.

  1. Hello

    I have a problem with that 2×2 W Amp (TBA820M)
    I made the pcb, soldered the components and all looks fine, but it doesnt work… at all…

    The traces are ok, the connections are like they should be… any ideas what could be the reason?

  2. I LIKE THIS CICUIT

  3. I MAKE IT BUT IT WAS NOT WORK .NOT HAVE ANY GAIN PLEASE HELP ME

  4. causes great discomfort to my anus. 9/10 its ok – IGN

  5. Compare your scheme with the tracks lay-out, check it’s nescessary Voltage 12 up to 16VDC and compare the scheme with the ic -data.pin outs.Possible you work with a damaged ic, so replace if an other new one works well. Don’t you miss a pot. at the input? Your scheme is probably a test circuit.The circuit with the load to ground will probably work better, I guess.This is an application.
