Thanks for the assistance.
the FAQ at
and the SigmaDSP Evaluation Boards at
both list evaluation board EVAL-ADAU1442EBZ,
However I can not locate a data sheet the that gives the specifics of that particular evaluation board.
this page generates an error for me
basically this page only lists 6 data sheets for SigmaDSP evaluation boards
while this page lists 8 boards
one of the missing ones is the one I wanted to study tonight
