GENERAL DESCRIPTION
The EVAL-ADXL314Z is a simple evaluation board that allows quick evaluation of
the performance of the ADXL314, a 3-axis digital accelerometer. The EVAL-
ADXL314Z is ideal for the evaluation of the ADXL314 in an existing system
because the stiffness and the small size of the EVAL-ADXL314Z minimize the
effect of the board on both the system and acceleration measurements.
For full details on the ADXL314, see the ADXL314 data sheet, which should be
consulted in conjunction with this user guide when using the EVAL-ADXL314Z
evaluation board.
EVALUATION BOARD PHOTOGRAPH
EVALUATION BOARD HARDWARE
The EVAL-ADXL314Z includes a 10-pin Harwin connector that provides robustness
for the more demanding scenarios and access to all power and signal lines.
Four holes are provided that are set at 2.54 mm × 2.54 mm at the corners of
the printed circuit board (PCB) for mechanical attachment of the EVAL-ADXL314Z
to the application fixture. An external host processor is required for
communication to the device.
The dimensions of the EVAL-ADXL314Z are 35.5 mm × 35.5 mm.
EVALUATION BOARD CIRCUITRY
The EVAL-ADXL314Z is equipped with three factory-installed capacitors for
bypass: two 0.1 μF capacitors (C1 and C2) and a 1.0 μF capacitor (C3). C2 and
C3 are VS bypass capacitors for reducing analog supply noise and C1 (located
between VDD I/O and GND) is for reducing digital clocking noise. The schematic
of the EVAL-ADXL314Z is shown in Figure 2. The 10-pin Harwin mating female
connector is M80-8881005, and the preassembled cable part number is
M80C108373C. These two components are not included in the evaluation kit.
See the ADXL314 data sheet for information on configuring the accelerometer
following its connection to the application host pro-cessor. 
EVALUATION BOARD HARDWARE
HANDLING CONSIDERATIONS
The EVAL-ADXL314Z is not reverse polarity protected. Reversing the VS or
VDDI/O supply and GND pins can cause damage to the ADXL314. Dropping the EVAL-
ADXL314Z on a hard surface can generate several thousand g of acceleration,
which can exceed the absolute maximum ratings data sheet limits. See the
ADXL314 data sheet for more information.

ESD Caution
ESD (electrostatic discharge) sensitive device. Charged devices and circuit
boards can discharge without detection. Although this product features
patented or proprietary protection circuitry, damage may occur on devices
subjected to high energy ESD. Therefore, proper ESD precautions should be
taken to avoid performance degradation or loss of functionality.
