GENERAL DESCRIPTION
The ADXL346 is a small, thin, ultralow power, 3-axis accelerometer
with high resolution (13-bit) measurement at up to ±16 g. Digital
output data is formatted as 16-bit twos complement and is acces-
sible through either an SPI (3- or 4-wire) or I2C® digital interface.
The ADXL346 is well suited for mobile device applications. It
measures the static acceleration of gravity in tilt-sensing appli-
cations, as well as dynamic acceleration resulting from motion
or shock. Its high resolution (4 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 by
comparing the acceleration on any axis with user-set thresholds.
Tap sensing detects single and double taps in any direction. Free-
fall sensing detects if the device is falling. Orientation detection
is capable of concurrent four- and six-position sensing and a
user-selectable interrupt on orientation change for 2D or 3D
applications. These functions can be mapped individually to
either of two interrupt output pins. An integrated, patent pending
memory management system with 32-level first in, first out (FIFO)
buffer can be used to store data to minimize host processor activity
and lower overall system power consumption.
Low power modes enable intelligent motion-based power
management with threshold sensing and active acceleration
measurement at extremely low power dissipation.
The ADXL346 is supplied in a small, thin, 3 mm × 3 mm ×
0.95 mm, 16-lead, plastic package.
