EVAL-AD4696FMCZ
GENERAL DESCRIPTION
The EVAL-AD4696FMCZ is designed to demonstrate AD4696
performance and provide access to its many configuration options
via an easy to use ACE plugin graphical interface. The AD4696 is a
16-channel, 16-bit, 1 MSPS, multiplexed successive approximation
register (SAR) analog-to-digital converter (ADC) that enables
high performance data acquisition of multiple signals in a small
form factor. The AD4696 employs easy drive features and on-chip
channel sequencing that simplify hardware and software designs
and allow it to fit into a variety of space constrained precision
multichannel applications.
The EVAL-AD4696FMCZ allows users to quickly evaluate the
performance of the AD4696 with no or minimal hardware
modifications. The hardware includes two externally driven analog
input channels for evaluating ac performance and 14 channels
with dc levels generated on board for evaluating dc and settling
performance. The externally driven channels have configurable
drive circuitry and interface with precision signal generators via
SMA connectors.
The AD4696 ACE plugin communicates with the EVAL-
AD4696FMCZ hardware through the EVAL-SDP-CH1Z controller
board. The software allows AD4696 device configuration via a
register map view and easy to use GUIs. The software also enables
performing analog-to-digital conversions and provides time
and frequency domain analysis tools for quick evaluation of the
AD4696.
More detailed feature descriptions and device specifications are
provided in the AD4696 data sheet and must be consulted in
conjunction with this user guide when using the EVAL-
AD4696FMCZ. Full details on the EVAL-SDP-CH1Z are
available on the SDP-H1 product page.
