Hi all,

i'm new to this forum and i want to make a power amplifier with TDA1557Q.

Can anyone please provide me the layout.http://www.electro-tech-online.com/i...cons/icon9.gif

That circuit is so simple it doesn't need a PCB!

Look at the datasheet to see how much current it uses for the load and supply voltage.

Now use a trace calculator tool to work out the trace width you require for each connection.

Doesn't the datasheet give an example PCB layout?, they often do for such amps.

none of the datasheet i've found give the pcb layout and the main problem is it will not compatible with normal 2.54mm veroboard.

Make yourself a PCB then; it's not that hard and there's plenty of info on how to do it on this forum, just use the search feature.
