Abstract
This analog-to-digital converter includes a comparator (20) to which the samples X.sub.(n) of the signal to be converted, are applied. The output of the comparator controls a logic circuit (22) producing (N+1) bits to a digital-to-analog converter (24) the output of which is fed back to the input of comparator (20). The converter carries out a converting procedure through N successive approximation steps at the end of which the N most significant bits available at the output of the logic circuit (22) stand directly for the rounded-off digital value of sample X.sub.(n).
