Accelerometer

ADXL325

GENERAL DESCRIPTION

The ADXL325 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 selects 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.

The ADXL325 is available in a small, low profile, 4 mm ×

4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package

(LFCSP_LQ).
