I made this mtda1543 dac. This can accept usb and digital audio input. It is designed with eight of tda1543.
I found there were a few tda1543 da converter on the web. But I didn't found any module, which accept digital audio input and usb together. That's why I design this module.
Dimensions are 170 x 116 mm

I designed LM3886 Power Amplifiers.
This power amp are in dual and the Watt is depends on the input power voltage.
8Ohm based, then 50watt need +/-35Voltate(dc).
Used capacitors are silver mica,wima etc.
