EVALUATION BOARD CIRCUITRY

The EVAL-AD5675SDZ/EVAL-AD5675RSDZ
allow the function and performance of the
to be easily tested. Each evaluation board contains two voltage
regulators that generate the analog and digital power supplies
and that also power the SDP-B
regulators are powered via a 6 V supply attached to Connector J3.
Alternatively, a separate analog supply can be attached via
Connector J2, and an external V
to Connector J1.

SDP-B board, which is attached to Connector J4. The
board allows the software provided with the kit to be used to
load register values, set the voltage of the DAC outputs, and
write to the control register of the AD5675/AD5675R. When
the SDP-B board is not required, the control signals can be
applied to the AD5675/AD5675R
relevant pins on Connector J5.
The DAC output voltages are available on the SMB connectors,
VOUT0 to VOUT7.
