Hello everyone;

i want to make a project with PCM2707 bus powered but i need GND isolation from usb-pc ;

i was thinking to use DCR01 Miniature, 1W Isolated Regulated DC/DC Converter for isolation but i don't know if usb bus differential line is working without reference to it`s own GND (from PC).

I really need to avoid using a full galvanic isolation module for usb (costly and used space)

... or maybe i will just try it to see if works
