Novel Hall IC gives 90°outputs from many different magnets

Allegro has used two-dimensional Hall sensing to deliver quadrature outputs from a variety of magnet rings. Its point is, that if both Hall sensors on a chip are in the same plane, then outputs are only 90° out of phase for magnets of one particular pole period – related to the distance between the two ...
