A process and device for providing an analog-to-digital conversion employing a successive approximation principle is provided. The search interval from a value X to a Value Y, which represents the value interval in which an unknown analog signal is to be converted to a digital signal value, is divided into a number of smaller search intervals, being divided into different area for employing a successive approximation process to iterate to the desired digital signal value. Further, reference levels are defined for each search interval to coincide with at least one other reference level, where coinciding reference level belongs to two search intervals formed by areas in a nearest larger search interval. |
