Abstract
A method for detecting errors of an A/D converter which is designed for converting an analog input signal into a digital output signal. The digital output signal represents a number z which results from an input value of the analog input signal when an A/D conversion is carried out. In the method, a value range for all possible numbers z is subdivided into subranges, and a value range for all possible input values is subdivided into subranges and an input value and a number z corresponding thereto are associated in each case with subranges which correspond to one another. In the method, a check is made to determine with which subrange an input value which is to be converted is associated, and with which subrange a number which is ascertained by the A/D converter is associated. An error is detected when the number and the input value are associated with subranges which do not correspond to one another.
