DESCRIPTION
The DEM-DAI1604 demonstration board provides an
ideal platform for evaluating the performance and
operation of the PCM1604 six-channel audio digital-
to-analog converter. Demonstration software is in-
cluded for controlling the PCM1604’s programmable
functions. The D/A converter outputs are filtered and
passed on to RCA jacks for connection to audio
measurement equipment and commercial audio gear.
A digital audio receiver allows connection to S/PDIF
data streams, while an on-board connector provides an
interface to audio Digital Signal Processors (DSP) and
decoders.
