Abstract:
1. An integrated circuit, comprising: a lead frame; a first substrate having first and second opposing surfaces, wherein the first substrate is coupled to the lead frame; a second substrate having first and second opposing surfaces, wherein the first substrate and the second substrate are coupled such that the first surface of the second substrate is proximate to the first surface of the first substrate and the second surface of the second substrate is distal from the first surface of the first substrate; an electronic component disposed on the first surface of the first substrate; a first magnetic field sensing element disposed on the first surface of the second substrate; and a second magnetic field sensing element disposed on the first surface of the first substrate wherein the first magnetic field sensing element provides a first sensitivity to a magnetic field, wherein the second magnetic field sensing element provides a selected second different sensitivity to the magnetic field, and wherein the integrated circuit is configured to provide a first operating range responsive to the first magnetic field sensing element and a second selected different operating range responsive to the second magnetic field sensing element.
