ABSTRACT:
A technique for determining an offset-reduced Hall voltage (Uh), and/or an offset voltage (UH, offset) of a Hall sensor (1) includes applying a Hall sensor current (I) at first and second taps (a1, a2, a3) of the Hall sensor (1), and determining a first Hall voltage (Uh1) at third and fourth taps (a3, a4) displaced from the first and second taps (a1, a2, a5). A second Hall sensor current is applied modified relative to the first, and a second Hall voltage (Uh2) is determined. The Hall voltage (Uh) and/or Hall voltage offset (Uh,offset) are determined from the first and second Hall voltages. To compensate any offset present, a second measurement applies the second Hall sensor current I at taps (a3, a4) that are spatially displaced relative to the first and/or second taps.
