Abstract: The present disclosure relates to a design for operating an angle sensor. A first sensor signal is output from a first sensor element on the basis of a magnetic field, which is dependent on an angle of rotation of a measurement object, at the location of the first sensor element. A second sensor signal is output from a second sensor element on the basis of the magnetic field that is dependent on the angle of rotation of the measurement object at the location of the second sensor element. During a calibration mode of the angle sensor, in which a rotation of the measurement object is performed, a first offset value of the first sensor signal, a second offset value of the second sensor signal and an amplitude correction value are determined on the basis of signal amplitudes of the first and second sensor signals. The first and second offset values ascertained during the calibration mode and the amplitude correction value are stored for use in an operating mode of the angle sensor.
