ALS31313 3-D Linear Hall-Effect Sensor

ALS31313 3-D Linear Hall-Effect Sensor

TheALS31313 3DMAG™ linear Hall-effect sensor IC provides a 12-bit digital value corresponding to the magnetic field measured in each of the X, Y, and Z axes. The ALS31313 is preconfigured for use in 3D sensing applications for head-on linear motion, slide-by position sensing, and rotation angle meas.
