ST’s digital compasses integrate a 3-axis digital accelerometer with a 3-axis digital magnetic sensor in a single LGA package.
Designed to accurately detect the direction and magnitude of external magnetic fields, ST’s compasses use accelerometer measurements for tilt compensation, thus ensuring very accurate compass heading even when portable devices are inclined.
ST’s low-noise e-compasses offer 2 mgauss resolution and a wide range of full scales, all selectable by the user: from ±2 to ±16g full scale acceleration, and from ±1.3 to ±16 gauss magnetic field full scale.
The compass family includes embedded self-test and smart power functionalities to minimize current consumption.
