1. A galvanomagnetic sensor array system comprising:

  • an array of galvanomagnetic elements, wherein at least three galvanomagnetic elements make up the array; and

    a processor coupled to receive each output signal from the array of galvanomagnetic elements, wherein the processor and array of galvanomagnetic elements are integrated in a single semiconductor die;

    a differential amplifier coupled to receive at a first terminal thereof a signal constituting the output signal from any selected one of the galvanomagnetic elements, the amplifier further coupled to receive at a second terminal thereof an offset signal selectable to remove bias that may be present in the output signal of the selected galvanomagnetic element.
