Abstract
A circuit configuration for converting analog signals to digital signals, having a multiplexer which has a plurality of analog signal inputs, an address input that is several bits wide and an output, and which is configured to connect one of the analog signal inputs to the output when an address assigned to the respective analog signal input is applied to the address input, and having an analog/digital converter, whose input is connected to the output of the multiplexer in order to digitize the respective analog signal emitted at the output. The circuit configuration includes at least one test signal source for supplying a test signal to a subset of the analog signal inputs of the multiplexer. In addition, an address is assigned to each of the analog signal inputs of this subset, of whose bits one has a first binary value, and all the others have a second binary value that is different from the first.
