Abstract

According to a method for operating a Hall sensor assembly, at least two values (I1, I2) of an input signal (I) of a Hall sensor (11) of the Hall sensor assembly (10) having different magnitudes are set and the associated values (V1, V2) of an output signal (V) of the Hall sensor (11) are determined. Furthermore, a residual offset value (k, VOFF) of the output signal (V) is determined according to the values (V1, V2) of the output signal (V) that were determined at the at least two values (I1, I2) of the input signal (I).
