Overview

The LIS2MDLTR is an ultra-low-power, high-performance three-axis magnetoresistive sensor designed for magnetic field sensing. It offers a wide dynamic range of +/- 50 gauss and supports both I2C and SPI digital interfaces, making it highly versatile for motion tracking and compass applications.

Why Choose This Part

This sensor features a high resolution of 16 bits and a sensitivity of 1.5 mgauss/LSB, ensuring precision in weak magnetic fields. Its low-power architecture is notable, consuming only 50 microamps in low-power mode at 20Hz, which is ideal for battery-operated wearables.

Applications

Electronic Compass
Provides accurate heading information for handheld devices and robotics by sensing the Earth's magnetic field.
Magnetometry
Used in industrial settings for magnetic field mapping and metal detection tasks.
Indoor Navigation
Assists in dead-reckoning systems where GPS signals are unavailable by providing orientation data.
Position Sensing
Detects the presence and orientation of magnets in contactless switches or lid-sensing applications.
