LIS3MDL: three-axis digital output magnetometer
Introduction
This document is intended to guide in the usage of and to provide useful details related to ST’s
LIS3MDL 3-axis digital magnetometer.
The LIS3MDL is a three-axis high-performance magnetic sensor with a 16-bit resolution and a full scale
of ±4/±8/±12/±16 gauss (user-selectable).
Sensor low-power consumption combined with power saving operating modes enables targeting
handheld portable applications such as cell phones and tablets.
The ultra-small size and weight of its small, thin, plastic, land grid array package (LGA-12 2x2x1) make
it an ideal choice for any application where reduced package size and weight are required, helping to
optimize placement on the board.
Thermal stability of the device is guaranteed, internally compensating sensitivity drift over temperature
variations using an advanced embedded algorithm.
To support integration in smart applications, the device may be configured to generate interrupt signals
using thresholds programmable by the end user on the fly.
External communication is managed by a digital I²C/SPI serial interface standard output.
The device is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
ST software support available for the LIS3MDL includes drivers, a tilt-compensated electronic compass,
dynamic magnetometer calibration, 6-axis virtual gyro and complete 9-axis sensor fusion.
