Switching arrangement for evaluating analog measurement values, particularly for motor vehicles

摘要

In a switching arrangement for evaluating analog measurement values which are supplied to an analog/digital converter via an analog multiplexer, the reference voltage of the analog/digital converter is derived from the output signal of a second analog multiplexer, the inputs of which are supplied with the feed voltages of the signal transmitters. Derivation of the reference voltage from the feed voltages of the signal transmitters results in a voltage fluctuation compensator even with different feed voltages for the signal transmitters.
