STMicroelectronics 3-Axis Surface Mount Sensor, LGA, 12-Pin

ST’s e-Compasses include combo solutions built around a 3-axis digital accelerometer with a 3-axis digital magnetic sensor in a single LGA package, as well as standalone 3-axis digital magnetic sensors for designing solutions where the magnetic sensor must be located in a specific position on a printed circuit board. Designed to accurately detect the direction and magnitude of external magnetic fields, ST’s e-Compasses use accelerometer measurements for tilt compensation, thus ensuring very accurate compass headings even when handheld or mobile devices are inclined.
