EVALUATION BOARD SOFTWARE
SOFTWARE DESCRIPTION
The AD7795 evaluation board is shipped with a CD-ROM
containing software that can be installed onto a standard PC
to control the AD7795. The software uses the USB of the PC to
communicate with the AD7795, via the cable that accompanies
the board.
The software allows you to configure the AD7795 and to read
conversion data from the AD7795.
Data can be read from the AD7795 and displayed or stored for
later analysis. For further information, see the AD7795 data
sheet available at www.analog.com.
INSTALLING THE SOFTWARE
To install the software
1. Start Windows® and insert the CD-ROM.
2. The installation software should launch automatically. If it
does not, use Windows Explorer to locate the file setup.exe
on the CD-ROM. Double-click this file to start the

describes the various menu and button options on the main
window. The Registers, Other Registers, and Temp Demo
sections describe the most commonly used evaluation software
windows.
The data that has been read can be exported to other packages,
such as MathCAD™ or Microsoft® Excel, for further analysis.
On power-up, the AD7795 evaluation board software configures
the device to have a gain of 64, the internal reference is selected,
the AIN1(−)/AIN1(−) channel is selected, the bias voltage is
