Need decent layout for a TDA2050.

Jidis · 23rd November 2009, 07:57 PM

Is there a nice ready to etch layout or Eagle files floating around anywhere for this amp? I know it's a simple circuit, I just want something that's already been arranged for decent low noise. I'll probably be doing a stereo pair or maybe two monos.

Thanks!

George

There certainly is! DIY TDA2050 Hi-Fi Chip Amplifier (chipamp) Everything you need is on that page. I built one of those myself recently. With +/- 25V rails I plays surprisingly well.

Looks like what I need olof102!

-Thanks!

Or you may use that layout which I designed may be six years ago for LM1875.. But useable for TDA20XX also. I can send the eagle files if you need.

Thanks Ozgur!

I think I'm straight on the one from the datasheet now though. I had already cleaned it up and printed it. I've now got two of them etched, and will be working on a power supply board and the actual speaker enclosures.

Take Care,

George

The PCB from datasheet is generating and working not very well, GND is traced not wery good, becouse it is going near Vin and etc.
