EVALUATION BOARD HARDWARE

POWER SUPPLIES

To use the evaluation board with the
power supply is required, which is connected to Connector J3.
The evaluation board can be used without the
in which case, the J1 and J2 connectors are used as the power
supply inputs.
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location close
to the AD5675/AD5675R. It is recommended that AGND and
DGND not be connected elsewhere in the system to avoid
ground loop problems.
All supplies are decoupled to ground with 10 µF tantalum and
0.1 µF ceramic capacitors.

INPUT SIGNALS

When the SDP-B board is used to control the evaluation board,
the digital input signals are applied to Connector J4. When the
SDP-B board is not used, apply the digital signal to Connector J5.

OUTPUT SIGNALS

The DAC output voltages are available on the SMB connectors,
VOUT0 to VOUT7.
