3-Axis, ±200 g Digital Accelerometer Evaluation Board

GENERAL DESCRIPTION

The EVAL-ADXL375Z is a simple evaluation board that allows
quick evaluation of the performance of the
digital accelerometer. The EVAL-ADXL375Z
0.1 inch spaced vias, for population of a 4-pin and 5-pin header,
for access to all power and signal lines. The vias or headers
allow the evaluation board to be attached to a prototyping
board (breadboard) or attached to the PCB in an existing
system. Four holes are provided for mechanical attachment
of the EVAL-ADXL375Z to the application. An external host
processor is required for communication to the part.
The dimensions of the EVAL-ADXL375Z
with mounting holes set 15 mm × 15 mm at the corners of the
printed circuit board (PCB).

CIRCUIT DESCRIPTION

The schematic of the EVAL-ADXL375Z
See the ADXL375 data sheet for configuration of the
accelerometer after it is connected to the application host
processor.
The PCB layout of the EVAL-ADXL375Z
The EVAL-ADXL375Z has three factory installed capacitors for
bypass: two 100 nF capacitors and a 10 μF capacitor. C1 and C2
are V bypass capacitors to reduce analog supply noise and C3,
S
located between V and GND, is provided to reduce digital
DD I/O
clocking noise.

HANDLING CONSIDERATIONS

The EVAL-ADXL375Z is not reverse polarity protected. Reversing
the V or V supply and GND pins can cause damage to the
S DD I/O
ADXL375.
Dropping the EVAL-ADXL375Z
several thousand g's of acceleration, which may exceed the data
sheet absolute maximum limits. See the
for more information.
