Arrangement for converting an input voltage signal, which can fluctuate within a wide range, into a binary output signal

摘要

The subject-matter of the invention is an arrangement for converting an input voltage signal, which can fluctuate within a wide range, into a binary output signal. The arrangement contains a detector, which changes its binary output signal from one binary state to the other binary state at a specific value of the input signal, and a current limiting circuit. The current limiting circuit is a constant current source (16), which is adjusted, as a function of at least one voltage limit value matched to the range of an operating voltage signal, to a low constant current at higher input voltages and to a higher constant current at smaller input voltages.
