Claim 16:
17. A sensor comprising:
a sensing element configured to generate a sensing element output signal indicative of a sensed parameter;
means for detecting which of a plurality of voltage ranges a supply voltage of the sensor falls within and generating a supply voltage 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;
means for performing a fine sensitivity control on the sensing element output signal; and
means for performing a coarse gain adjustment and a coarse offset adjustment on the sensing element output signal, the coarse gain adjustment and the coarse 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,
wherein performing the coarse gain adjustment find the coarse 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.
