GETTING STARTED

SOFTWARE INSTALLATION

Download the

ACE

evaluation software from the EVAL-

AD4696FMCZ product page. Both the EVAL-AD4696CFMCZ
software and the

EVAL-SDP-CH1Z

(SDP-H1) board drivers

must be installed.

Warning

The ACE evaluation software and drivers must be installed
before connecting the EVAL-AD4696FMCZ and the SDP-H1 to
the USB port of the PC to ensure that the evaluation system is

correctly recognized when it is connected to the PC.

Installing the ACE Evaluation Software

To install the ACE evaluation software, take the following steps:
1.

Download the ACE evaluation software to a Windows®-
based PC.

Double click the
