Kit Overview

The EVAL-ADXL325ZEVAL-ADXL325Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL325ADXL325 three-axis accelerometer. The small size (1" x 1") of the breakout board makes it easy to mount the accelerometer to an existing system without the need for additional hardware and with minimal effect on performance of the system and of the accelerometer.

The EVAL-ADXL325ZEVAL-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 ADXL325ADXL325.
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).

The ADXL325ADXL325 is a small, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±5 g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration, resulting from motion, shock, or vibration.

The user can select the bandwidth of the accelerometer using the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins. Bandwidths can be selected to suit the application with a range of 0.5 Hz to 1600 Hz for X and Y axes and a range of 0.5 Hz to 550 Hz for the Z axis.

Note: 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.

Key Applications: Mobile devices, Mobile devices, Disk drive protection, Image stabilization, Sports and health devices
