Abstract

An analog-digital converter includes a differential amplifier having collector resistances each being in the form of a resistance line. Node points between resistance segments of the resistance lines are in the form of output terminals. Comparators with a balanced input are provided in the same amount as the resistance segments. In each case one input of a comparator is connected to an output terminal of a first resistance line and another input of the comparator is connected to an output terminal of a second resistance line. Therefore, the same resistance value in each case acts between two output terminals, which are connected to one comparator, in the collector circuit of the differential amplifier.
