The invention relates to an automatic offset compensation method for an analog-digital converter according to patent document DE 43 33 908. Analog-digital converters according to patent document DE 43 33 908 can be configured for different input signal sizes. To this end, the offset of the reference signal (sinusoidal signal) must be held constant. The causes problems, especially in the case of small amplitude values of the reference signal. The aim of the invention is to hold the offset of the reference signal constant by means of an automatic control. The inventive offset control does not require any balancing and carries out its function without using any precision elements.
