Abstract
A sensor device contains a first magnetic field sensor chip having a first sensor element. The first magnetic field sensor chip is configured to detect a component of a magnetic field at the location of the first sensor element. The sensor device contains a second magnetic field sensor chip having a second sensor element. The second magnetic field sensor chip is configured to detect a component of a magnetic field at the location of the second sensor element. The sensor device contains a current conductor configured to carry a measurement current that induces a magnetic field at the locations of the sensor elements. The magnetic field sensor chips and the current conductor are arranged relative to one another in such a way that an influence of a homogeneous magnetic stray field on the first components is compensated for upon difference formation or summation applied to the first components.
