Evaluation Board User Guide
EVALUATION BOARD HARDWARE
POWER SUPPLIES
The following external supplies must be provided:
•
•
The analog and digital planes are connected at one location,
close to the AD5570. To avoid ground loop problems, it is
recommended AGND and DGND not be connected elsewhere
in the system.
Each supply is decoupled to the relevant ground plane with
10 µF and 0.1 µF capacitors. Each device supply pin is also
decoupled with a 10 µF and 0.1 µF capacitor pair to the
relevant ground plane.
LINK OPTIONS
The link options on the evaluation board should be set for the
required operating setup before using the board. The functions
of the link options are described in Table 3.

Description
LK1 is used in conjunction with LK2 to select whether the on-board ground force sense buffer is used.
When LK1 and LK2 are inserted, the ground force sense buffer is not used, the ground pins are connected directly to 0 V, and
the buffer is removed from the ground loop.
When LK1 and LK2 are removed, the ground force sense buffer is used.
This link is used to select the internal or the external reference.
When LK3 is inserted, the on-board reference is selected as the voltage reference source for the AD5570.
When LK3 is removed, an external voltage reference can be applied to Connector VREF.
