OPERATING WITH THE EVAL-BOARD
CONTROLLER
The evaluation board can be operated in a stand-alone
mode or operated in conjunction with the EVALUA-
TION-BOARD CONTROLLER. This EVALUATION-
BOARD CONTROLLER is available from Analog
Devices under the order entry "EVAL-CONTROL
BRD2". When operated with this control board, all sup-
plies and control signals to operate the AD7898 are pro-
vided by the EVALUATION-BOARD CONTROLLER
when it is run under control of the AD7898 software
which is provided with the AD7898 evaluation board
package (mode 1 operation only). This EVALUATION-
BOARD CONTROLLER will also operate with all Ana-
log Devices evaluation boards which end with the letters
CB in their title.
The 96-way connector on the EVAL-AD7898CB plugs
directly into the 96-way connector on the EVALUA-
TION-BOARD CONTROLLER. No power supplies are
required in the system. The EVALUATION-BOARD
CONTROLLER generates all the required supplies for
itself and the EVAL-AD7898CB. The EVALUATION-
BOARD CONTROLLER is powered from a 12V ac
transformer. This is a standard 12V ac transformer ca-
pable of supplying 1A current and is available as an acces-
sory from Analog Devices under the following part
numbers:
EVAL-110VAC-US:
For use in the U.S. or Japan
EVAL-220VAC-UK:
For use in the U.K.
EVAL-220VAC-EU:
For use in Europe
These transformers are also available for other suppliers
including Digikey (U.S.) and Campbell Collins (U.K.).
Connection between the EVALUATION-BOARD CON-
TROLLER and the serial port of a PC is via a standard
RS-232 cable which is provided as part the EVALUA-
TION-BOARD CONTROLLER package. Please refer to
the manual which accompanies the EVALUATION-
BOARD CONTROLER for more details on the EVALU-
ATION-BOARD CONTROLLER package.
