ABSTRACT:
One embodiment of the invention is directed to a method of extending the input range of an analog-to-digital converter (ADC) having a nominal input voltage range. The method comprises an act of mapping an over-range input voltage that falls outside of the nominal input voltage range to an over-range digital output code. Another embodiment of the invention is directed to an apparatus comprising an ADC having a nominal input voltage range, wherein the ADC is adapted to map an over-range input voltage that falls outside of the nominal input voltage range to an over-range digital output code.
