GENERAL DESCRIPTION

The ADA4570 is an anisotropic magnetoresistive (AMR) sensor
with integrated signal conditioning amplifiers and analog-to-digital
converter (ADC) drivers. The ADA4570 produces two differential
analog output pairs that indicate the angular position of the sur-
rounding magnetic field.

User Guide | EVAL-ADA4570
The EVAL-ADA4570SDZ evaluation board features the ADA4570 in
an end of shaft magnet configuration.
The evaluation kit is composed of the EVAL-ADA4570SDZ and
a magnetic stimulus on a printed circuit board (PCB) mount. To in-
terface to a computer, the EVAL-SDP-CS1Z (SDP-S) or the EVAL-
SDP-CB1Z (SDP-B) is required which must be ordered separately.
An illustration of the ADA4570 evaluation system consisting of
the PC graphic user interface (GUI), the SDP, and the EVAL-
ADA4570SDZ is shown in
Figure
to either the SDP-S or the SDP-B interface card.
The EVAL-ADA4570SDZ allows a detailed evaluation of the
ADA4570 where the software GUI demonstrates angular measure-
ment and performs system level calibration.
The EVAL-ADA4570SDZ also provides access via a standard
header for power and digital signals to the on-board ADC interface
(AD7266), which allows evaluation of the ADA4570 with a user
preferred microcontroller platform and to start the system software
development. Users can also access the analog output signals
of the ADA4570 to a user preferred ADC with a microcontroller
platform.
The PCB is designed so that the sensor board can be detached
from the SDP interface to provide a smaller form factor. Power
supplies can be sourced from either the USB port via the SDP card
or an external bench supply.
