Abstract
An analog/digital converter system includes a multiplexer, which includes multiple channels having at least one switch, and an analog/digital converter, the analog input of which is connected to the output portal of the multiplexer. Also described is a method for checking a multiplexer for an analog/digital converter. At least one other switch for testing the multiplexer is provided in at least one channel, this other switch connecting the input portal and/or the output portal of the corresponding channel and/or the corresponding channel to a predefined voltage potential.

An analog/digital converter system, comprising:
- a multiplexer which includes multiple channels having at least one switch, the at least one switch connecting an input portal of the channel to a corresponding output portal;
- and
- an analog/digital converter, an analog input of which is connected to the output portal of the multiplexer;
- wherein there is at least one other switch for testing the multiplexer in at least one of the channels, the at least one other switch connecting at least one of the input portal and the output portal of the corresponding channel and/or the corresponding channel to a predefined voltage potential.
A method for checking a multiplexer for an analog/digital converter, the multiplexer including multiple channels having at least one switch which are switched, the method comprising:
- connecting an input portal of the particular channel to a corresponding output portal, wherein there is at least one other switch for testing the multiplexer in at least one channel;
- and
- connecting the input portal and/or the output portal of the corresponding channel and/or the corresponding channel to a predefined voltage potential with the aid of this other switch.
