EVAL-AD5600PMDZ

EVALUATION BOARD HARDWARE

POWER SUPPLIES

The EVAL-AD5600PMDZ requires an external source for the
analog and digital supply. See Table 2 for more details.
Both AGND and DGND inputs are provided on the EVAL-
AD5600PMDZ. The AGND and DGND planes are connected
at one location close to the AD5600. To avoid ground loop
problems, it is recommended that AGND and DGND not be
connected elsewhere in the system.
All supplies are decoupled to ground with 10 µF tantalum and
0.1 µF ceramic capacitors.

TEST POINTS

The EVAL-AD5600PMDZ has various test points for debugging
and monitoring purposes. These test points are described in
Table 3.

VOLTAGE REFERENCES

The EVAL-AD5600PMDZ has an on-board voltage reference
with a value of 2.5 V. Note that the
an external supply through the AVDD connector (see Table 2).

LINK OPTIONS

A number of link options are incorporated on the EVAL-
AD5600PMDZ and must be set for the required operating
conditions before using the board. The functions of these link
options are described in Table 4.
