 is a small, low-power, 3-axis linear accelerometer and 3-axis 

magnetometer combined into a single package. The device features a 
selectable I

2

SPI serial interface with 14-bit accelerometer 

and 16-bit magnetometer ADC resolution along with smart-embedded 
functions. 

 has dynamically selectable acceleration full scale 

ranges of ±2 g/±4 g/±8 g and a fixed magnetic measurement range of 
±1200

μT. Output data rates (ODR) from 1.563 Hz to 800 Hz are selectable by 

the user for each sensor. Interleaved magnetic and acceleration data is 
available at ODR rates of up to 400 Hz. 

 is available in a plastic 

QFN package and it is guaranteed to operate over the extended temperature 
range of -40 °C to +85 °C.
