<DIV>I have the ADAU-1701 eval board. I picked/ordered that first.
Then I discovered the temp spec was not quite as good as we needed and
considered the 1401A. But then came across the 1772 and it is supposedly
better for when you need to port the digital audio IO to a fpga, which we
do. Lower latency and different IO implementation I think. Still a
SigmaDSP part but has less bells and whistles – we did not get our eval board
for it yet. Read an article about interfacing it to fpga’s that seemed to
favor it. I’ve never worked with codecs but only one around with any analog
experience so I got the responsibility to choose our codec. Ughh. I
never had the need to design a board since the Music Man days really so someone
else here will do that. So do you think the miniDSP USB streaming kit
thing is as simple as hooking some jumpers between it and the 1772 eval board or
will there need to be a bit of custom hardware involved? </DIV>
