Reducing the input response of the analog comparator
You can selectively delay the output of an analog
comparator by means of the ”On-delay” and ”Off-delay”
special functions. With on-delay, output Q is only set if the
pulse width of the triggering signal at input Trg (=analog
comparator output) is longer than the on-delay time.
Using this method, you will obtain a virtual hysteresis and
reduce the input response to short signals.
