USB-S/PDIF converter and DAC

[EUVL]

If I am not mistaken, any of the popular ones like M2Tech, Musiland, XMOS, .. are all around 150 USD and are all asynchronous, AND will do 24/192.

I've made some major changes to the circuit. In addition to its primary function as a USB to S/PDIF converter, it can be built up to create a battery-powered headphone amp. The amp input can be switched between USB or analog (e.g. an MP3 player). The Li-ion battery is switched up to +/- 5V to run the parallelled opamps that drive the headphones, and is charged from the USB power.
The PCB was laid out to fit directly into a Hammond 1457K1201 enclosure.

Hello Paul,
You may want to look at the attached Web site... USB DAC w/ I2S output plus other frills.

Yes, looks pretty similar. I didn't need an I2S output.
