ABSTRACT:
A description is given of a circuit arrangement with a resistor voltage divider chain which comprises a number N of two-terminal resistors which are connected in series between a number N+1 of connection points, with N being greater than or equal to 2. In order to monitor the operating state of the resistor voltage divider chain, there is proposed an arrangement having at least two comparator stages with in each case two input terminals, each of which is connected to in each case one of the connection points such that each of the resistor elements is bridged by the input terminals of at most one of the comparator stages, and with in each case one output terminal for outputting a comparator output signal having a first logic level when corresponding signals are fed to the input terminals and otherwise having a second logic level, and a switching stage which has in each case one input terminal for connection to each of the output terminals of the comparator stages and is designed to form an error signal by logic switching of the comparator output signals in order to indicate an error when at least one of the comparator output signals has a first logic level.
