TDA2009 amplifier stereo 10W

The IC-TDA2009 amplifier circuit on stereo 10W+10W design that looks similar to the IC 8W +8 W stereo amplifier circuits of the previous album.But it will change the IC amplifier as a number TDA2009. Within the IC for circuit amplifiers, Hi-Fi class AB.And output short circuit protection sectors as well.But there will be different according to the properties of the IC.

TDA2009 Datasheet

The TDA2009 IC is to qualify from the power supply 8-24 volts, the current maximum of 1-2 amp.An output voltage watt 10 watt 24 volt load 4 ohms, 0.351% distortion at a frequency 1 kHz, frequency response from 10 Hz-50 kHz at -3 dB to 36 dB of gain and the strength. input signal at 100 mV.

When raising the power supply circuit and input into the audio input.The audio input left channel and right channel. Will it work the same.So I explained the principles of the left channel only one box. The signal through C1 for protection dc electric To interfere with IC.

Then go to the input signal to pin 5 of IC.The non inverting pin will not extend to phase signals. The output from pin 8. Through C8 and to prevent DC and increase the low frequency response the better,then sent to the speaker.The C10 and C11 serve to filter the light to protect the smooth sound … Tub..Tub… at the time of launch noise.

This is PCB layout of this circuit, notice: C-220uf = C-470uF

  1. Hi,
    this was very useful page and i wish to assemble an amplifier with TDA2009A.

    Can you please tell me from where i can purchase the PCB for this..?
    is it EE149? I checked this for online but disappointed?
    Is it available with the retail stores?

    Please help me.

  2. It’s a good amplifier for beginners in audio domain or schools student, highschool student, higher school university student, in understanding the principle of amplifiers, and then going to more complex circuit of amplifiers.
    The specifications of this amplifier its not so good for an audiophile , but for a person who want a cheap amplifier its good , the ratio cost/performance its good.

  3. hey i am basically searching for a 2.1 channel to make. so does the tda2009 process only the treble??? i am confused. please can you help me.

  4. Tda 2009 Ata dia ki 5w +5w bajano jabe

  5. this was vary usfull to me i made this sound amp and also iam i it its working super

  6. Can we use 10w 8inch speker in tda2009

  7. Hi Any one want any Pcb of any type feel free to call me ….. 09826588782

  8. Hi any one required any type of pcb feel free to call me…. any time @09826588782

  9. It works well but when I increase the volume on my phone, there is noise on the speaker.

  10. Hi, this is great thing it is working very well.
    I am using 5W speakers until I find 10W speakers, but can I connect on output and pair of a bass speakers, will that work and how many watts it can be when there is 5W and how many when is 10W speakers conected?

  11. Hi ..
    I want ic2009 mono PCB
