GENERAL DESCRIPTION

The ADXL330 is a small, thin, low power, complete 3-axis

accelerometer with signal conditioned voltage outputs, all

on a single monolithic IC. 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 X and Y axes, and a range of

0.5 Hz to 550 Hz for the Z axis.

The ADXL330 is available in a small, low profile, 4 mm × 4 mm

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

(LFCSP_LQ).
