EVALUATION BOARD HARDWARE

The EVAL-ADA4571-2 end of shaft evaluation system

comprises of a PCB with the AD7266 ADC and an external

mountable magnetic stimulus.

The ADA4571-2 evaluation system can be powered directly

from the host PC USB, directly from an external bench supply,

or through the on-board 5 V regulator, the ADP3336.

To power the motherboard through an on-board 5 V reference,

apply 6 V to 12 V across P3 to P5 and configure the jumpers

accordingly. If the bench supply features current-limiting, it is

recommended to set the current limit to 100 mA as a precaution.

JUMPER CONFIGURATION

Refer to the ADA4571-2 motherboard schematic, see Figure 13, to

understand the purpose of each jumper.

Configure the P10 motherboard default jumper as follows:

•

Install a jumper on P10 between VBUS and BRD_SUPPLY

to power the evaluation board through the USB connection

at the PC.

•

Alternatively, install a jumper on P10 between BRD_SUPPLY

and _SUPPLY to power the evaluation board through the

external bench supply

DEVICE UNDER TEST (DUT) OUTPUTS

The outputs of the ADA4571-2 can be monitored at the test

points located on the Evaluation board.

All outputs from the ADA4571-2 are also sampled by the on-

board ADC and are available in the GUI.
