EVALUATION BOARD SOFTWARE
SOFTWARE INSTALLATION
The
AD5761R
evaluation kit includes self installing evaluation
software on a CD. The evaluation software is compatible with
Windows XP or later Windows based PCs. If the setup file does
not run automatically, run
setup.exe
from the CD.
Install the evaluation software before connecting the evaluation
board and SDP-B board to the USB port of the PC to ensure
that the evaluation system is correctly recognized when
connected to the PC.
After installation from the CD is complete, power up the
EVAL-AD5761RSDZ evaluation board as described in the Power
Supplies and Default Link Options section. Connect the SDP-B
board (Connector A) to the evaluation board and then to the USB
port of your PC using the supplied cable.
When the evaluation system is detected, proceed through any
dialog boxes that appear to complete the installation.
SOFTWARE OPERATION
To launch the evaluation software, complete the following steps:
1.
From the
Start
menu, click
Analog Devices
>
AD5761R
>
AD5761R Evaluation Software
. The main window of the
software opens (see Figure 7).
2. If the evaluation system is not connected to the USB port
when the software is launched, a connectivity error
displays (see Figure 4). Connect the evaluation board to
the USB port of the PC, wait a few seconds, and click
Rescan.
Follow the instructions that appear.

MAIN WINDOW
The main window of the evaluation software is divided into two
tabs:
Configure
and
DAC
.
Begin by choosing the device to evaluate: the
AD5761R
(16-bit
resolution) or the
AD5721R
(12-bit resolution). Note that clicking
the
AD5721R
option allows the user to evaluate the
AD5761R
as a
12-bit DAC; there is no separate evaluation setup for the
AD5721R
.
A dialog box appears for this selection, as shown in Figure 5.

Configuration
The
Configure
tab allows access to the control register and the
mode of the daisy-chain functionality of the device. Figure 7
shows the
Configure
tab in the main window.
The
AD5761R
requires an initial command to write to the
control register to remove the output clamp to ground. A dialog
box appears as a reminder to write to the control register (see
Figure 6). During the same write, configure the
AD5761R
as
necessary to modify the default values for the power-up voltage
(
Power Up Voltage
), voltage output range (
Output Range
),
clear voltage (
CLEAR Voltage
), overrange (
OVR
), bipolar
range coding (
B2C
), thermal shutdown alter (
ETS
), and
internal reference mode (
IRO
). (See Figure 7.)
