GENERAL DESCRIPTION

The ADXL335 is a small, thin, low power, complete 3-axis accel-

erometer with signal conditioned voltage outputs. The product

measures acceleration with a minimum full-scale range of ±3 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

Bandwidths can be selected to suit the application, with a

range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range

of 0.5 Hz to 550 Hz for the Z axis.

The ADXL335 is available in a small, low profile, 4 mm ×

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

(LFCSP_LQ).
