1) over operating range, unless otherwise specified. Typical values correspond to V_S = 12 V and T_A = 25°C
2) To operate the sensor at the max. switching frequency, the magnetic signal amplitude must be 1.4 times
higher than for 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 switching
4) Jitter is the unpredictable deviation of the output switching delay
5) B_REP is equivalent to the noise constant
6) Time from applying V_S ≥ 2.7 V to the sensor until the output state is valid
7) Thermal resistance from junction to ambient
