Abstract: In the method, each approximation step contains weighing process for analog voltage signal in lower and top value of preset voltage interval. In weighting process of second approximation step two different reference voltages are used, dividing preset voltage interval into three partial voltage intervals. To each partial interval is allocated value and determined during weighting process, in which partial interval analog voltage signal is present. Determined partial interval, with allocated partial value, is used for forming digital value. Processing of weighting process of first approximation step is specified. Independent claims are included for A/D converter.
