OPERATING WITH THE EVAL-CONTROL BOARD
The evaluation board can be operated in a stand-alone
mode or operated in conjunction with the EVAL-CON-
TROL BOARD. This EVAL-CONTROL BOARD is
available from Analog Devices under the order entry
"EVAL-CONTROL BOARD". When operated with this
control board, all supplies and control signals to operate
the AD7476/77 are provided by the EVAL-CONTROL
BOARD when it is run under control of the AD7476/77
software which is provided with the AD7476/77 evaluation
board package. This EVAL-CONTROL BOARD will
also operate with all Analog Devices evaluation boards
which end with the letters CB in their title.
The 96-way connector on the EVAL-AD7476/77CB plugs
directly into the 96-way connector on the EVAL-CON-
TROL BOARD. No power supplies are required in the
system. The EVAL-CONTROL BOARD generates all
the required supplies for itself and the EVAL-AD7476/
77CB. The EVAL-CONTROL BOARD is powered from
a 12 V ac transformer. This is a standard 12 V ac trans-
former capable of supplying 1A current and is available as
an accessory from Analog Devices under the following
part numbers:
EVAL-110 VAC-US: For use in the U.S. or Japan
EVAL-220 VAC-UK: For use in the U.K.
EVAL-220 VAC-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 EVAL-CONTROL BOARD and
the serial port of a PC is via a standard RS-232 cable
which is provided as part of the EVAL-CONTROL
BOARD package. Please refer to the manual which ac-
companies the EVAL-CONTROL BOARD for more
details on the EVAL-CONTROL BOARD package.
