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 AD7475/AD7495 soft-

ware which is provided with the AD7475/AD7495 evalua-

tion board package . This EVALUATION-BOARD

CONTROLLER will also operate with all Analog De-

vices evaluation boards which end with the letters CB in

their title.

The 96-way connector on the EVAL-AD7475/AD7495CB

plugs directly into the 96-way connector on the EVALUA-

TION-CONTROL BOARD. No power supplies are re-

quired in the system. The EVALUATION-BOARD

CONTROLLER generates all the required supplies for

itself and the EVAL-AD7475/AD7495CB. The EVALU-

ATION-BOARD CONTROLLER is powered from a

12V ac transformer. This is a standard 12V ac transformer

capable of supplying 1A current and is available as an

accessory 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.
