DIY TDA2009 Amplifier

I've started home build audio amplifier using the TDA2009A, the power is 10W+10W and enough for me because I have small speaker.

The TDA2009A using from 8 to 24 V, and its very easy to build.

To do:

  • Drawing the schematic by Cadsoft Eagle.
  • Making the PCB.
  • Building and testing.
  • Making the box for amp.

Today I create schematic by Cadsoft Eagle. The first, Cadsoft Eagle is free for personal use, second they allow create use library, so it is first time I'm using the Cadsoft Eagle, that why I'm do it very slow.

The Cadsoft Eagle do not have TDA2009 library, so I'm being create a new library for TDA2009.



Next, draw the schematic, it is simply, but when switch to PCB to difficult to me :D



Buzzzzzzz, that all today, tomorrow will be continue...

That looks great. Would you mind sending me the tda2009a part for eagle? I'm trying to make a pcb for it too, but i've never used eagle before either.

Hello!!
I'm trying to build an amplifier and I'm having a little problem, then I found your schematics and wondered if I could use your TDA2009A for eagle. Would you mind sending it to me? It would be really nice.

Hi! Good job!
I'm starting a project with TDA2009A, but i have the same problem: no tda in the library! Can you send to me the eagle tda lib and the eagle pcb for tda2009 amp? I don't have so much time for design task, so i've found in your work a good starting point, anyway i've to make some mods in the schema, like the driver for balanced inputs and some other minor things! Thank you :)
