This project is a set of two DAC's made for my friend. The first one is NOS-DAC designed by Peter Daniel based on TDA1543 and CS8412 SPDIF receiver. The other one is a little modified version of USB PCM2702 DAC from TI application note.
The heart of this part is low-cost 16-bit Philips DAC. As a SPDIF decoder was choosen Cirrus Logic CS8412 IC with SN75179 as an input driver. Each IC have it's own AN800x regulator and there are separate wireing for alalog and digital section.
