Abstract:
Embodiments relate to sensor device configurations. In one embodiment, a sensor device comprises a bias magnet, a field sensor die, a first set of one or more magnetic field sensor elements, a second set of one or more magnetic field sensor elements, a memory, and circuitry. The sensor device is configured to combine the sensed magnitudes from each of the magnetic field sensor elements of the first set to obtain a first set output, trim the sensed magnitudes from each of the one or more magnetic field sensor elements of the second set with one of the set of trim values to obtain a second set output, and combine the second set output with the first set output to provide an output signal.
