Hi Team,
Could you please recommend the proper solution for 4 DMIC Audio codec(USB2.0) request?
If not one chip can support, please provide the combination for this design is acceptable.

Hi, Scott,
Unfortunately, we don't have a device with 4 DMIC support and USB interface. I can recommend you the PCM1864 as the front-end for the solution, as this device supports up-to four digital microphones. However, we don't have an USB-audio device capable of interfacing four channels of audio from the TDM (or 2×I²S) data of the PCM1864 to the USB host device.
