An analog-digital converter has a first register for holding a first approximation number which is variable in a first cycle and is fixed in a second cycle, as well as a second register for holding a second approximation number which is fixed in the first cycle and is variable in the second cycle. Further, the analog-digital converter has an adder for adding the first and second approximation numbers and for providing a sum approximation number representing a digital representation of an analog input signal. A processor is formed to calculate the first approximation number and the second approximation number. Further, the analog-digital converter has a controller for operating the processor in the first or second cycle.
