EVAL-AD7273/AD7274
SOCKETS
There are six input sockets relevant to the operation of the
AD7273/AD7274 on this evaluation board. The functions of
Table 5. Socket Functions
Socket Function
J1 Subminiature BNC socket for AIN analog input.
J2 Subminiature BNC socket for analog input to bias-up
circuit, VIN.
J3 Subminiature BNC socket for AIN analog output from
bias-up circuit, VBIASED.
OPERATING WITH THE EVAL-CONTROL-BRD2
The evaluation board can be operated in a standalone mode or
operated in conjunction with the EVAL-CONTROL BOARD,
which is available from Analog Devices under the order entry
EVAL-CONTROL-BRD2. When operated with this control
board, all supplies and control signals to operate the AD7273/
AD7274 are provided by the EVAL-CONTROL-BRD2. Software
to communicate with the Control Board and AD7273/AD7274
is provided with the AD7273/AD7274 evaluation board
package. This EVAL-CONTROL-BRD2 also operates with all
Analog Devices evaluation boards that end with the letters CB.

Subminiature BNC socket for analog input to SDATA
pin on ADC.
Subminiature BNC socket for analog input to SCLK pin
on ADC.
Subminiature BNC socket for analog input to CS pin
on ADC.
The 96-way connector on the EVAL-AD7273/AD7274CB plugs
directly into the 96-way connector on the EVAL-CONTROL-
BRD2. The EVAL-CONTROL-BRD2 provides all the supplies
for the evaluation board. It is powered from a 12 V ac trans-
former. This is a standard 12 V ac transformer capable of
supplying 1 A current and is available as an accessory from
CONNECTORS
There are four connectors on the AD7273/AD7274 evaluation

Connector Function
J4 96-way connector used to interface to the EVAL-
CONTROL-BRD2.
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 from other suppliers,
including Digi-Key Corporation (U.S.) and Campbell Collins,
Ltd. (U.K.).

External +12 V, ?12 V and AGND power connector.
External V REF power connector.
Connection between the EVAL-CONTROL-BRD2 and the
serial port of a PC is via a standard printer port cable, which is
provided as part of the EVAL-CONTROL-BRD2 package. Refer
to the manual that accompanies the EVAL-CONTROL-BRD2
for more details on the EVAL-CONTROL-BRD2 package.
