The ADXL345 is a three-axis accelerometer with high resolution (13-bit).Its measurement is up to ±16g. Digital output data is accessible through either a SPI (3- or 4-wire) or I2C digital interface and is formatted as 16-bit twos complement.

It 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.Several special sensing functions are provided.

Features:

• SPI and I2C interfaces

• Low Power: 25 to 130uA @ 2.5V

• Up to 13bit resolution at +/-16g

• 1.8V to 3.6V supply

• Tap/Double Tap detection

• Activity/Inactivity monitoring

• Free-Fall detection

Dimensions: 3 x 5 x 1mm LGA
