Looks like a brand new part. Digi-Key does not have stock of the
chip yet. Probably will need to go straight through AKM. Perfect
part, though, if we can get it in a timely manner.<br>
<br>
There are 3 parts, AK5534, AK5554 and AK5574 with increasing
performance, pin-compatible. The AK5534 is in stock at DK for $4.21
and has quite good performance itself. It looks like we could
develop with it and upgrade later.<br>
<br>
There are data sheets, but no sign of stock of any of the
development boards, AKD5534-B, AKD5554-B, AKD5574-B.<br>

<div> I can't find the evaluation board anywhere, though.
Seems like it would be a good idea to use one in
development. (AKM55X4-B). Where is that found?</div>

is an AKM 4-channel part that has extremely good THD+N and
dynamic <br>
range and can do the full 192kHz bandwidth. It can run up
to 768kHz <br>
sample rate with even greater bandwidth. It also has DSD
output that <br>
would allow custom filters.<br>

$13.02 from Digi-Key single part price!<br>
