PCM2903C: USB differential I/O pins not used

Genius 16270 points
Part Number: PCM2903C

Tool/software:

Hi Experts,

We would like to ask about the PCM2903C. When D+ and D- are not connected to the USB port, but the integrated circuit will still be powered, will audioIN and audioOUT be use like connection to the to the amplifier connection?

Question is if it is possible to use the IC without connecting D+ and D-. Or what happen when D+ and D- will be disconnected but powering will be still. Whole IC stop working?

Regards,
Archie A.
