GENERAL DESCRIPTION

The ADXL326 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 ±16 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

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 ADXL326 is available in a small, low profile, 4 mm ×

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

(LFCSP_LQ).
