DESCRIPTION
The DEM-DAI1602 demonstration board provides an
ideal platform for evaluating the performance and
operation of the PCM1602 6-channel audio Digital-to-
Analog converter (DAC). Demonstration software is
included for controlling the PCM1602’s programmable
functions. The DAC 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 onboard connector provides an interface to
audio Digital Signal Processors (DSP) and decoders.
