Small, Low Power, 3-Axis ±2 g Accelerometer ADXL327 FEATURES GENERAL DESCRIPTION 3-axis sensing
The ADXL327 is a small, low power, complete 3-axis accelerometer
Small, low profile package
with signal conditioned voltage outputs. The product measures
4 mm × 4 mm × 1.45 mm LFCSP
acceleration with a minimum full-scale range of ±2 g. It can
Low power: 350 μA typical
measure the static acceleration of gravity in tilt-sensing
Single-supply operation: 1.8 V to 3.6 V
applications, as well as dynamic acceleration, resulting from
10,000 g shock survival
motion, shock, or vibration.
Excellent temperature stability
The user selects the bandwidth of the accelerometer using
Bandwidth adjustment with a single capacitor per axis
the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
RoHS/WEEE lead-free compliant
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
APPLICATIONS
0.5 Hz to 550 Hz for the Z axis.
Cost-sensitive, low power, motion- and tilt-sensing applications
The ADXL327 is available in a small, low profile, 4 mm ×
Mobile devices
