Abstract

The invention relates to a magnetic-field sensor with a Hall effect device, a power supply, and an evaluating facility, which can be supplied with a Hall signal from the Hall-effect device and comprises an input amplifier, a storage element, and a signal superposition unit. To improve the accuracy of the magnetic-field sensor, in a first phase, a balancing signal for balancing the measurement-signal path with respect to an interface can be produced with the evaluating facility, the balancing signal being storable in the storage element, and in a second phase, the balancing signal stored in the storage element can be applied through the signal superposition unit to the interface, where it is superimposed on a Hall signal.
