An analog-digital converter includes a decision unit configured to evaluate a comparison potential in a decision step to obtain a comparison result; a number of charging units each comprising a switchable capacitor and an associated reference potential source, wherein each charging unit is configured to change the comparison potential by connecting the reference potential source to the switchable capacitor; and a control unit configure to successively switching one of the charging units following a previous decision step wherein, depending on the obtained comparison result the comparison potential is applied with a predetermined charge by the one respective charging unit, and wherein at least two of the charging units have an associated reference potential source providing different reference potentials.
