Electrical Characteristics
Product characteristics include the spread of values guaranteed within the specified voltage and ambient
temperature range. typical characteristics are the median of the production (at V_s=12V and T_A=25°C).

1) See Figure 6
2) To operate the sensor at maximum switching frequency, the value of the magnetic signal amplitude must be 1.4 times
higher than the static fields. This is due to the -3 dB corner frequency of the low pass filter in the signal path.
3) Systematic delay between magnetic threshold reached and output.
4) Jitter is the unpredictable deviation of the output switching delay.
5) Time from applying V_S. > 2.7 V to the sensor until the output state is valid.
6)Relationship between junction and ambient temperature: T_J=T_amb + R_thja . (V_S . I_S + V_QS . I_Q).
