GENERAL DESCRIPTION
The high performance
3-axis accelerometer with high resolution (13-bit) and selectable
measurement ranges up to ±8 g. The
leading noise and temperature performance for application
robustness with minimal calibration. Digital output data is
formatted as 16-bit twos complement and is accessible through
either a SPI (3- or 4-wire) or I
The
applications. It measures the static acceleration of gravity in tilt-
sensing applications, as well as dynamic acceleration resulting
from motion or shock. Its high resolution (2 mg/LSB) enables
measurement of inclination changes of less than 1.0°.
Several special sensing functions are provided. Activity and
inactivity sensing detect the presence or lack of motion and if
the acceleration on any axis exceeds a user-set level. Tap sensing
detects single and double taps. Free-fall sensing detects if the
device is falling. These functions can be mapped to one of two
interrupt output pins.
Low power modes enable intelligent motion-based power
management with threshold sensing and active acceleration
measurement at extremely low power dissipation.

1.2 mm, 16-lead cavity laminate package.
