GENERAL DESCRIPTION
The E VA L-AD7770FMCZ/EVA L -AD7771FMCZ/
EVA L-AD7779FMCZ evaluation kit features the AD7770,
AD7771, and AD7779 24-bit, analog-to-digital converters
(ADCs). The board interfaces with the system demonstration
platform SDP-H1 controller board (E VA L-SDP-CH1Z). The
SDP-H1 controller board supplies power to the EVAL -
AD7770FMCZ/EVA L -AD7771FMCZ/EVAL -AD7779FMCZ
evaluation board and also connects to a PC running a Windows®
operating system via a USB cable. The AD777x evaluation software
fully configures the AD7770, AD7771, and
AD7779 d
evice
register functionality and provides dc and ac time domain
analysis in the form of waveform graphs, histograms, and
associated noise analysis for ADC performance evaluation.
The E VA L-AD7770FMCZ/EVA L -AD7771FMCZ/EVAL -
AD7779FMCZ evaluation board allows the user to evaluate the
features of the ADC. The user PC software executable controls
the AD7770, AD7771, and AD7779 over the USB cable through
the SDP-H1 controller board.
Full specifications for the AD7770, AD7771, or AD7779 are
available in the AD7770, AD7771, or AD7779 data sheets and
should be consulted in conjunction with this user guide when
working with the evaluation board.
