The USB DAC/Receiver
The USB DAC/Receiver module is based on the Texas Instruments PCM2707 USB DAC chip (16-bit/48-kHz).
We utilize the standardized USB input and I2S or S/PDIF (selectable) output for feeding our other DAC modules. The DAC's single-ended analog outputs
are also available for use, allowing this module to function as a standalone DAC as well. Power for the USB module is provided by the USB bus, no power supply is required.
