ADXL330
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
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 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).
