GENERAL DESCRIPTION
The ADXL330 is a small, low power complete three axis
accelerometer with signal conditioned voltage outputs, all
on a single monolithic IC. The product measures acceleration
with a minimum full-scale range of ±2 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
capacitors C
Bandwidths may be selected to suit the application, with a
range of 0.5 Hz to 1,600 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).
