Comparator circuit

摘要

The invention is direct to a comparator circuit that maps an analog input signal into a digital output signal and comprises a threshold as well as an upper and a lower hysteresis threshold. Given transgression of the upper or lower hysteresis threshold by the analog input signal, at least one unlatch signal is formed that enables the switching of the digital output signal when the analog input signal upwardly transgresses the threshold. Independently of at least one unlatch signal, the digital output signal is inventively switched when the analog input signal transgresses the upper or lower hysteresis threshold.
