Abstract
A delta-sigma D/A converter, by which a digital valued, input signal is convertible into a binary, clock signal time discrete, output signal. By forming an average value of the output signal over a number of clock signal cycles, an analog value of the input signal can be displayed. The delta-sigma D/A converter is embodied in such a manner that, in use, it provides the output signal by serial arrangement of signal patterns of a set of signal patterns, wherein the signal patterns of the set are, in each case, binary, clock signal time discrete and extend over a signal pattern cycles total of a plurality of clock cycles. At least two signal patterns of the set have mutually different signal pattern average values, which are formed over the respective signal pattern cycles total, and all signal patterns of the set have, in each case, essentially the same number, especially exactly the same number, of edges.
