A circuit configuration for obtaining a binary output signal from a current signal delivered by a magnetic-field sensor comprises a magnetic-field sensor, a voltage-supply unit, a measuring device, a signal-conditioning stage, a control stage, wherein the signal values represent the two current values of the current signal, alternating in pulse shape, as supplied by the magnetic-field sensor, for supplying the currently obtained first and second signal values to a memory device after every pulse-shaped change in the current signal and for identifying a digital changeover-threshold signal in accordance with a first algorithm from the real-time first and second signal values, the memory device for storing the currently obtained first and second signal values, a digital/analogue converter stage, and a comparator.
