Guys,

I tried to connect TDA7266 with VS1053,

When I separate power supply between VS1053 and TDA7266....it works,
but when I combine them in one transformer, it doesn't work...

What's missing here ?
I use 1 Ampere Transformer with maximum output 30VA..

Thanks
 

How can I make a decoupler ?
12V for TDA7266 and 5V for ATmega...
