DESCRIPTION
The DEM-PCM1702 is an evaluation fixture for Burr-
Brown’s sign-magnitude, 20-bit digital-to-analog con-
verter, the PCM-1702. It is primarily intended for
quick evaluation of the PCM1702P’s spectral purity
and sound fidelity.
Two PCM1702s are provided to allow full stereo
evaluation. The input to the DEM-PCM1702 can be
the output serial data from DEM-PCM1760 (Burr-
Brown’s evaluation fixture for its 20-bit A/D and
digital filter, the PCM1760 and DF1760), or other
digital signal source through the interface connector.
The number of digital input data bits and optional
functions are selectable by switches on board.
The analog output signal is filtered by a GIC type low
pass filter (dual OP AMP) and the filtered output
appears on the output connectors (BNCs).
