Abstract
For improved offset compensation, a Hall sensor is provided with a device for orthogonally switching the Hall detector supply current and the Hall-voltage taps. A summing device determines an offset-compensated Hall-voltage value from first and second predetermined Hall-voltage values. The Hall-voltage values are formed by means of a Hall detector containing at least first and second Hall cells for offset-voltage precompensation. The first and second Hall cells are identical and are orthogonally switchable. The geometrical orientation of the first and second Hall cells includes an angle other than 0.degree. and 180.degree..
