The ADXL346 is a *all, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to &plu*n;16g. Di*al output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I²C® di*al interface.

The ADXL346 is well suited for mobile device 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 (4 mg/L*) 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 *all, thin, 3 mm × 3 mm × 0.95 mm, 16-lead, plastic package.
