ABSTRACT:
A successive approximation analog/digital converter converting an analog input signal into a digital output value by means of a plurality of successive conversion cycles, comprises at least one first input for injecting an analog input signal, a controllable capacitive network which is connected downstream of the first input and which is divided into at least two capacitive subnetworks and, at least two parallel-connected and parallel-operating comparators for defining a number of comparator thresholds which corresponds to the number of parallel comparators. The comparators are respectively connected downstream of one of the capacitive subnetworks and the comparators output a corresponding number of digital intermediate signals on the basis of the comparisons in the comparators. The analog/digital converter further comprises a register set by the intermediate signals. The register buffer-stores digital intermediate values for the respective intermediate signals and produces control signals for actuating the capacitive subnetworks in response to the content of the intermediate signals.
