1) Latch-up test with factor 1.5 is not covered. Please see max ratings also.
2) For operation at the maximum switching frequency the magnetic input signal must be 1.4 times higher than for static fields.
This is due to the -3dB corner frequency of the internal low-pass filter in the signal path.

Electrical and Magnetic Characteristics
Product characteristics involve the spread of values guaranteed within the specified voltage and ambient
temperature range. Typical characteristics are the median of the production and correspond to V_DD = 12 V and
TA = 25°C. The below listed specification is valid in combination with the application circuit shown in Figure 3-1
and Figure 3-2

1) Not subject to production test, verified by design/characterization.
2) Output jitter is the 1σ value of the output switching distribution.
3) Systematic delay between magnetic threshold reached and output switching.
4) Time from applying V_DD = 3.0 V to the sensor until the output is valid.
