Multichannel Audio Codecs for SigmaDSP

Question asked by tristantech on Nov 22, 2014

I'm using the ADAU1451 in an upcoming design and am picking out audio codecs to use alongside it. The SigmaDSP's serial audio ports theoretically support 8 or 16 channels each, but it seems like none of Analog's codecs ever send more than two channels (L/R) on one data line. The AD1938, for example, has 8 DACs but requires 4 separate serial ports! --and I'm running out of pins.

 

Are there any codecs available that make use of the additional channels in the serial port so that I can push data to a codec with many DACs using only one serial port?

 

Thank you for your help.
