Small, Low Power, 3-Axis 3 g
iMEMS® Accelerometer
ADXL330
FEATURES
GENERAL DESCRIPTION
3-axis sensing
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.
Small, low-profile package
4 mm × 4 mm × 1.45 mm LFCSP
Low power
180 μA at VS = 1.8 V (typical)
Single-supply operation
1.8 V to 3.6 V
10,000 g shock survival
Excellent temperature stability
BW adjustment with a single capacitor per axis
RoHS/WEEE lead-free compliant
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.
APPLICATIONS
Cost-sensitive, low power, motion- and tilt-sensing
applications
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).
