Abstract
A method for converting an analog input signal into a digital value with successive approximation. A first comparison operation is provided before a first approximation, which subdivides a predefined input voltage interval into five partial intervals according to four reference potentials. During the comparison operation, a partial voltage interval determined is used in the ensuing approximation for the selection of a new reference potential pair to be used. This method enables higher sampling rates. At the same time, the range of the input signal is increased.
