CONNECTORS
There are ten connectors on the AD7280A evaluation board.
The functions of these connectors are outlined in Table 7.
Connector J1 is used to interface with the EVAL-CED1Z board.
Connectors J2 and J3 are used to connect the AD7280As to
the battery cells. Connectors J1, J2, and J3 are inserted on the
AD7280A evaluation board when the board is packaged. The
remaining connectors, J4 to J7 and J14 to J16, are not inserted.

DAISY-CHAINING TWO OR MORE AD7280A
EVALUATION BOARDS
The AD7280A evaluation board includes two connectors, J15
and J16, which allow two or more AD7280A evaluation boards
to be daisy-chained together. A connection should be made
between J16 on the evaluation board connected to the DSP/
microprocessor, measuring voltage on battery cells 1 through
12, and connector J15 on the evaluation board connected to
battery cells 13 through 24.
The default setting of each AD7280A evaluation board is for
the master pin on Device 0 to be tied to V
resistor, R88. Each board also includes an option to solder a
resistor, R89, from the master pin to V
two or more evaluation boards, the R88 resistor on slave boards
