Device for measuring the strength of a magnetic field has first and second sensor devices linked to an evaluating circuit in a combined casing

摘要

As split-drain MOSFET components, first (11) and second (12) sensor devices fix on first and second locations respectively, on which a magnetic field to be measured is orientated with its amount balanced equally but set up as antiparallel. Both sensor devices are integrated as a solid state. An evaluating circuit (30) is integrated with the sensor devices on a substrate (40) as a solid state. An Independent claim is also included for a magnetic field sensor for the device for measuring the strength of a magnetic field and for a device for measuring current strength.
