GENERAL DESCRIPTION
The EVAL-AD7961FMCZ is an evaluation board designed to
demonstrate the low power AD7961 performance (16-bit,
5 MSPS PulSAR® differential ADC) and to provide an easy-to-
understand interface for a variety of system applications. A full
description of the AD7961 is available in the data sheet and
should be consulted when utilizing this evaluation board.
The user PC software executable controls the evaluation board
over the USB through the Analog Devices, Inc., system
demonstration platform board (SDP), EVAL-SDP-CH1Z.
On-board components include the following:
ADR4520/ADR4540/ADR4550: high precision, buffered band
gap 2.048 V/4.096 V/5.0 V reference options
AD8031: reference buffer
ADA4899-1/ADA4897-1: a signal conditioning circuit with
two op amps and an option to use a differential amplifier
(ADA4932-1)
ADP7102, ADP7104, ADP124, and ADP2300: regulators to
derive necessary voltage levels on board
This evaluation board interfaces to the SDP board via a 160-pin
FMC connector. SMA connectors, JP1/JP4 and JP2/JP5, are
provided for the low noise analog signal source.
