EVALUATION BOARD HARDWARE

The EVAL-ADA4570SDZ end of shaft evaluation system comprises
a PCB with the ADA4570, an AD7266
mountable magnetic stimulus.

CONFIGURATION OF THE EVAL-ADA4570SDZ

The EVAL-ADA4570SDZ was designed to provide flexibility for
users. The following configurations are available:
SDP and Analog Devices, Inc, software controlled
►
Using an external digital interface
►
A direct analog interface with the
►
If an external power supply is connected to supply the EVAL-
ADA4570SDZ, the current limitation of the external power supply
must be set to 100 mA as a precaution.
SDP and Analog Devices Software Controlled
The ADA4570 evaluation system can be powered directly from
the host PC USB by the SDP controller board via the P3 connec-

connect to P3 (see SDP and Analog Devices Software
The Connector P3 pinout with the used SDP connections for the
EVAL-ADA4570SDZ is listed in
configuration for the user to quickly achieve high performance
measurement.
This configuration uses the SDP to communicate with the
ADC to sample the sensor output and display the data with the
software provided.
