Preliminary Technical Data

DESCRIPTION

The EVAL-ADXL325Z is a simple evaluation board that allows

quick evaluation of the performance of the ADXL325 three-axis

accelerometer. The EVAL-ADXL325Z has a 6-pin, 0.1 inch

spaced header for access to all power and signal lines that the

user can attach to a prototyping board (breadboard) or wire

using a standard plug. Four holes are provided for mechanical

attachment of the EVAL-ADXL325Z to the ADXL325.

The dimensions of the EVAL-ADXL325Z are 20 mm × 20 mm

with mounting holes set 15 mm × 15 mm at the corners of the

printed circuit board (PCB).

CIRCUIT DESCRIPTION

The schematic of the EVAL-ADXL325Z is shown in Figure 1.

Analog bandwidth can be set by changing the C2, C3, and C4

capacitors. See the ADXL325 data sheet for a complete des-

cription of the operation of the accelerometer.

The part layout of the EVAL-ADXL325Z is shown in Figure 2.

bandwidth to 50 Hz (see Figure 1). Many applications require a

different bandwidth, in which case the user can change C2, C3,

and C4 as appropriate.

SPECIAL NOTES ON HANDLING

The EVAL-ADXL325Z is not reverse polarity protected.

Reversing the +V supply and ground pins can cause damage to

the ADXL325.

Dropping the EVAL-ADXL325Z on a hard surface can generate

acceleration greater than 1000 g, which may exceed the data

sheet absolute maximum limits. See the

for more information.
