GENERAL DESCRIPTION

The EVAL-AD7173-8SDZ
AD7173-8, a 24-bit, 31.25 kSPS analog-to-digital converter
(ADC) with integrated analog input buffers, on-board power
supply regulation, and an external amplifier section for
amplifier evaluation. A 7 V to 9 V ac-to-dc adapter is regulated
to 5 V and 3.3 V; this supplies the
components. The
USB port via the system demonstration platform (SDP)
EVAL-SDP-CB1Z (SDP-B)
The AD717x Eval+ software fully configures the
device functionality via a user accessible register interface and
provides dc time domain analysis in the form of waveform
graphs, histograms, and associated noise analysis for ADC
performance evaluation.
