Triple Axis Accelerometer - ADXL345BCCZ
Triple Axis Accelerometer - ADXL345
Description: The ADXL345 is a
small, thin, low power, three-axis accelerometer with high resolution
(13-bit) measurement up to ±16g. Digital output data is formatted as
16-bit twos complement and is accessible through either a SPI (3- or
4-wire) or I2C digital interface.
The ADXL345 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 (4mg/LSB) enables resolution of inclination changes of as
little as 0.25°.
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 interrupt output pins. An integrated 32 level
FIFO can be used to store data to minimize host processor intervention.
Low power modes enable intelligent motion-based power management with
threshold sensing and active acceleration measurement at extremely low
power dissipation.
