Preliminary Technical Data
EVAL-AD7798EB
After the AD7798 Evaluation Board Software has been installed, connect the board to the PC via J1 on the AD7798 Evaluation Board
and the USB port on the PC using the supplied USB connector cable. The PC will automatically find the new USB device and will identify
it as: AD7798 Evaluation Board. Follow the onscreen instructions that appear automatically. During the installation process if the
following window appears:

SOCKETS
There are five sockets relevant to the operation of the AD7798 on this evaluation board. The functions of these sockets are outlined in
Table 3.
Table 3. Socket Functions
Socket
Function
AIN1+
Sub-Miniature BNC (SMB) Connector. The analog input signal for the AIN1(+) input of the AD7798 is
applied to this socket.
AIN1-
Sub-Miniature BNC (SMB) Connector. The analog input signal for the AIN1(-) input of the AD7798 is
applied to this socket.
REFIN+
Sub-Miniature BNC (SMB) Connector. This socket is used in conjunction with REFIN(-) to apply an
external reference to the AD7798. The voltage for the REFIN(+) input of the AD7798 is applied to this
socket.
REFIN-
Sub-Miniature BNC (SMB) Connector. This socket is used in conjunction with REFIN(+) to apply an
external reference to the AD7798.The voltage for the REFIN(-) input of the AD7798 is applied to this
socket.
J2
34 Pin (2x16) pin Straight Header. This Socket is used in conjunction with the prototype area to interface
any signal to the AD7798. It is specifically designed as a socket for a 34 pin header.
