Comparator circuit for triggering a switching process when a variable measurement signal passes through a switching threshold

摘要

A comparator circuit having a signal input and at least one signal output having an ON-state and an OFF-state, wherein the ON-state represents an input signal lying above a pre-given switching level Vs and the OFF-state represents an input signal lying below the switching level Vs. The comparator circuit has two comparators, the signal inputs of which are each acted upon by the input signal, wherein both the comparators are wired together in such a way that a switching on of the first comparator produces a signal corresponding to the ON-state of the comparator circuit and the switching off of the second comparator produces a signal corresponding to the OFF-state of the comparator circuit.
