Abstract
A magnetic field sensor apparatus includes a first magnetic field sensor and a second magnetic field sensor, arranged on a substrate in a spaced manner from each other, a first temperature sensor with an output for a first temperature sensor signal, a second temperature sensor with an output for a second temperature sensor signal, a first stress sensor with an output for a first stress sensor signal, and a second stress sensor with an output for a second stress sensor signal, wherein the first temperature sensor and the first stress sensor are arranged more closely to the first magnetic field sensor or at a location identical with the first magnetic field sensor, and the second temperature sensor and the second stress sensor are arranged more closely to the second magnetic field sensor than to the first magnetic field sensor or at a location identical with the second magnetic field sensor.
