OPERATING WITH THE EVAL-CONTROL-BRD2
The evaluation board operates in a standalone mode or in
conjunction with the EVAL-CONTROL-BRD2. This EVAL-
CONTROL-BRD2 is available from Analog Devices, Inc. under
the order entry EVAL-CONTROL-BRD2. All supplies and
control signals to operate the AD7328 are provided by the
EVAL-CONTROL-BRD2 when it is run under the control of
the AD7328 software that is provided with the AD7328
evaluation board package. This EVAL-CONTROL-BRD2 also
operates with all Analog Devices evaluation boards with the
letters CB in their titles.
The 96-way connector on the EVAL-AD7328CB plugs directly
into the EVAL-CONTROL-BRD2. No power supplies are
required in the system. The EVAL-CONTROL-BRD2 generates
the required supplies for itself and the EVAL-AD7328CB. The
EVAL-CONTROL-BRD2 is powered from a 12 V ac transformer.
This is a standard 12 V ac transformer capable of supplying 1 A
current and is available as an accessory from Analog Devices
under the part numbers found in
Table 6.
Table 6.
12 V AC Supply For Use In
EVAL-110VAC-US United States or Japan
EVAL-220VAC-UK United Kingdom
EVAL-220VAC-EU Europe
These transformers are also available from other suppliers
including Digi-Key (United States) and Campbell Collins
(United Kingdom).
Connection between the EVAL-CONTROL-BRD2 and the
parallel port of a PC is via an IEEE 1284-compliant cable
provided as part of the EVAL-CONTROL-BRD2 package.
For more details, refer to the manual that accompanies the
EVAL-CONTROL-BRD2 package.
