EVAL-AD7764_15 Datasheet, PDF (7/23 Pages) Analog Devices – Evaluation Board for AD7764/AD7765 using

Preliminary Technical Data
USING THE EVALUATION SYSTEM
HARDWARE CONNECTIONS
1. Apply power to the EVAL-CED1Z via +7V, 15W power
supply provided with the EVAL-CED1Z board. At this
stage, the green LED labeled ‘Power’ on the EVAL-CED1Z
should be lighting. This indicates that the EVAL-CED1Z is
receiving power The USB cable can then be connected
between the PC and the EVAL-CED1Z.
2. Connect the USB cable between the PC and the EVAL-
CED1Z. A green LED positioned beside the USB
connector on the EVAL-CEDZ board will light indicating
that the USB connection has been established.
3. Power up the EVAL-AD7764/AD7765EDZ evaluation
board through Connector J2. Connect a wire from the V+
labeled connector to 7.5 V of an external power supply. Also
ensure that there is a GND connection between the GND of
J2 and the power supply GND connection

4. Connect the female connector (J4, marked “CED1Z SPORT
Interface”), which is on the under side of the EVAL-
AD7764/AD7765EB evaluation board to the SPORT header
of the EVAL-CED1Z board. The SPORT header is located
on the left hand side of the EVAL-CED1Z board and is
marked in the silkscreen.
5. Start the EVAL-AD7764/AD7765EDZ software.
The differential input to the AD7764/AD7765 device can be
connected to the black connector XLR connector (J1) marked
“Differential Input.” This differential input is routed to the inputs
of the AD7764/AD7765/ on-board differential amplifier. As the
software will power up the AD7764/5 device it is advisable that
users do not apply an analog input until the device is fully
powered up.
With the hardware set up, you can now use the software to
control the EVAL-CED1Z and the AD7764/AD7765 evaluation
board. To launch the software, from the Analog Devices menu
click on the AD7764_5 submenu, then click on the AD7764_5
icon.
