1. An integrated device comprising:
at least one sensing circuitry arranged to be placed in proximity to an electrical conductor conducting a current, the at least one sensing circuitry comprising at least one magnetic field sensing element, and the at least one sensing circuitry configured to measure at least one quantity dependent on the current as a combination of outputs of the at least one magnetic field sensing element caused by the current flowing through the electrical conductor;
an input for sensing a measure of a voltage,
wherein the at least one magnetic field sensing element is arranged to be biased by a current derived from and/or related to the current into or out of the input, such that the output from the at least one magnetic field sensing element is related to the current through the electrical conductor and the current into or out of the input.
