EVALUATION BOARD CIRCUITRY

The

EVAL-AD5629RSDZ

EVAL-AD5669RSDZ

evaluation

boards easily test the function and performance of the

AD5629R

AD5669R

Control of the

AD5629R

AD5669R

is typically performed by

the

SDP-B

board, which is attached to Connector J3. The

SDP-B

board allows the software provided with the kit to load register
values, set the voltage of the DAC outputs, and write to the
control register of the

AD5629R

AD5669R

When the

SDP-B

board is not required, the control signals can

be applied to the

AD5629R

AD5669R

by connecting them to

the relevant SMB Connector J6 to Connector J9.
The DAC output voltages are available on the SMB Connector A to
Connector H.
