GENERAL DESCRIPTION
The
EVAL-AD7625FMCZ
/
EVAL-AD7626FMCZ
are evaluation
boards designed to demonstrate the low power performance of the
AD7625
/
AD7626
16-bit, 6 MSPS/10 MSPS PulSAR® differential
analog-to-digital converters (ADCs), and to provide an easy to
understand interface for a variety of system applications. Full
descriptions of the
AD7626
and
AD7625
are available in the
respective product data sheets, which should be consulted in
conjunction with this user guide when using this evaluation board.
The user PC software executable controls the evaluation board
over the USB cable through the Analog Devices, Inc., system
demonstration platform board (SDP) board,
EVAL-SDP-CH1Z
.
On-board components include: the
ADR3412
/
ADR4540
high
precision, buffered band gap 1.2 V/4.096 V reference options;
the
AD8031
reference buffer; the
ADA4899-1
/
ADA4897-1
signal conditioning circuit with two op amps and an option to
use a differential amplifier (
ADA4932-1
); and the
ADP7102
,
ADP7104
,
ADP124
, and
ADP2300
regulators to derive
necessary voltage levels on board.
These evaluation boards interface to the SDP board via a 160-pin
FMC connector. The SMA connectors (J3/J6 and J5/J8) are
provided for the low noise analog signal source.
