DIY TDA2009A Amplifier (Finish)

After 2 days, I'm continuing work, the TDA2009 amplifier was finished. The sound is suitable with my litle speaker. Today, I'm give them for my young brother, he very happy.


Next time, I'll make another and maybe I'll using TDA1557Q chipamp.

DIY TDA2009 Amplifier (continue)

One day hard work, now I've free time for continuing my TDA2009 Amp.
After 1 hour in market, I was bought:
  • TDA2009A
  • Resistors and Capacitors
  • PCB
  • Connector

The transformer taked from old VCD player.

Okie, now making the PCB...

Print layout to plain paper, cuting PCB and cleaning by water sand paper.

Prepering for iron, so today I'm very tired, tomorrow will be continuing work.

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...
