EVALUATION BOARD HARDWARE
POWER SUPPLIES
The following external supplies must be provided:
•
•
•
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location close
to the AD5764. It is recommended not to connect AGND and
DGND elsewhere in the system to avoid ground loop problems.
Each supply is decoupled to the relevant ground plane with 10 μF
and 0.1 μF capacitors. Each device supply pin is again decoupled
with a 10 μF and 0.1 μF capacitor pair to the relevant ground plane.
LINK OPTIONS
The position of Link 11 configures the board for either PC
control via the USB port (default setup) or for control by an
external source via J21 or the SMB connectors. The link options
on the evaluation board should be set for the required operating
setup before using the board. The functions of the link options
are described in Table 4.
.
12 V to 15 V between the AV
positive analog supply of the AD5764.
−12 V to −15 V between the AV
negative analog supply of the AD5764.
5 V between the 5 V and DGND inputs for the digital
supply of the AD5764 and digital circuitry. Alternatively,
place Link 1 in Position A to power the digital circuitry
from the USB port (default).
