This disclosure relates to a comparison device that receives an analogue input signal and a set value, and outputs a digital output signal. The device comprises a one-threshold comparator receiving the input signal and the set value, and the comparator generates a resultant signal that depends on the result of the comparison. Such a device comprises a sampler for sampling the resultant signal and a controller for blocking the sampler, after a switching of the input signal, as long as a timeout mechanism does not indicate that a given timeout duration has elapsed since the verification of a predetermined instability criterion. The timeout mechanism is reinitialized with the timeout duration every time that a predetermined instability criterion is satisfied. When the sampler is not blocked, it is used to copy the resultant signal at the output of the device.
