1. A sensor device for suppressing a magnetic stray field, the sensor device comprising:
a semiconductor body with a surface formed in an x-y plane and a back surface, the x-direction and the y-direction being formed orthogonal to one another, the semiconductor body being arranged on a substrate, the substrate and the semiconductor body being disposed in an IC package; a first pixel cell and a second pixel cell, the first and second pixel cells being formed in the surface of the semiconductor body together with a circuit arrangement, each of the first and second pixel cells having a first magnetic field sensor and a second magnetic field sensor, the first magnetic field sensor detecting a magnetic field in the x-direction and the second magnetic field sensor detecting a magnetic field in the y-direction, the first pixel cell being spaced apart from the second pixel cell along a connecting line; and an axis formed in a z-direction, the z-direction being configured orthogonal to the x-y plane; and a magnet having a planar main extension surface in the direction of the x-y plane and having a magnetization with four magnetic poles in the direction of the x-y plane, the surface of the semiconductor body being oriented parallel to the main extension surface of the magnet, wherein the magnet is mounted rotatable around the z-direction relative to an IC housing of the IC package, and an imagined lengthening of the axis penetrates the connecting line in the middle and penetrates the magnet in the center of gravity of the main extension surface of the magnet, wherein the IC package is spaced apart from the main extension surface of the magnet in the z-direction or the magnet is configured as a ring magnet formed in the x-y plane, and the IC package is arranged at least partially within the ring magnet, wherein the magnetic poles are arranged in the form of segments, and wherein the axis runs through the middle of the ring of the ring magnet. |
