Claim 11:
12. A method for providing a sensor comprising:
detecting which of a plurality of voltage ranges a supply voltage of the sensor falls within and generating a supply voltage signal, the supply voltage signal being a digital signal having at least a plurality of states, each of the plurality of states corresponding to a different one of the plurality of voltage ranges;
sensing a parameter with a sensing element to generate a sensing element output signal;
performing a fine sensitivity control on the sensing element output signal;
performing a coarse gain adjustment and a coarse offset adjustment on the sensing element output signal, the coarse gain adjustment and the course offset adjustment being performed based on the supply voltage signal, the coarse gain adjustment and the coarse offset adjustment being performed after the fine sensitivity control is performed on the sensing element output signal, and
generating, by an output driver, a sensor output signal that corresponds to the sensing element output signal,
wherein performing the coarse gain adjustment and the course offset adjustment includes generating one or more configuration signals and providing the one or more configuration signals to a coarse gain selection block and a coarse offset selection block, thereby causing: (a) the coarse gain selection block to adjust a gain of the sensing element output signal and (b) the coarse offset selection block to adjust an offset that is being applied to the sensing element output signal.
