General Description
The CDB5471 is an inexpensive tool designed to evalu-
ate the functionality/performance of the CS5471 2-
channel A/D Converter. In addition to this data sheet, the
CS5471 Data Sheet is required in conjunction with the
CDB5471 Evaluation Board.
Two terminal-block connectors serve as inputs to the
CS5471’s two analog input pairs. The CDB5471 in-
cludes an optional voltage reference source for CS5471.
A 4.096MHz crystal is provided as a source for CS5471’s
XIN pin, or an external clock source can be supplied by
the user. Digital output data from the CS5471 is trans-
ferred to the user’s IBM-compatible PC via the included
25-pin parallel port cable.
The CDB5471 includes PC software, allowing the user to
perform data capture (includes option for time domain
analysis, histogram analysis, and frequency domain
analysis). The software also allows real-time RMS calcu-
lation/analysis to be performed simultaneously on the
instantaneous data from both channels.
