Behaviour at magnetic input signals slower than T
Unlike the TLE4941 magnetic changes exceeding
of the TLE4941-2, even at f significantly lower than 1Hz. Depending on their amplitude edges
slower than
is not exceeded before a new initial self-calibration is started, the output of the corresponding
edge will be inhibited. This depends on signal amplitude and initial phase.

All additional parameters for TLE4942-2 are guaranteed by design, based on lab
characterisations. For series production additional to the parameters of TLE4942
