USB Audio DACs

For example, if you use a Raspberry Pi to "stream" radio broadcasts, you need a USB DAC, which can ideally be operated with standard audio drivers (for Linux).

For example, a good solution for a simple audio interface is to use a PCM2912 USB CODEC.

The circuit is so simple that the board can easily be etched by itself:

If the requirements are a bit higher, then a PCM2706PJTR in combination with a PCM1794ADBR is also a good choice.

I also completely revised the circuit board. Here you can see the 3D expression from KICAD:
