General Description
The AS5403 can measure magnetic fields components in all three dimensions and converts the magnetic field information into absolute position information.
Only a simple 2-pole magnet is required as the magnetic field source.
Using two 3D-Hall cells allows absolute (single pixel) as well as differential (double pixel) 3D magnetic field measurement.
The differential measurement makes the AS5403 ideal for use in rough automotive position sensing applications that include not only dust, dirt or moisture but also unwanted magnetic stray fields.
