1) _{To operate the sensor at the max. switching frequency, the value of the magnetic signal}
amplitude must be 1.4 times higher than for static fields. This is due to the -3dB corner frequency
of the low pass filter in the signal path.
2) _{Systematic delay between magnetic threshold reached and output switching.}
3) _{Jitter is the unpredictable deviation of the output switching delay.}
4) _{BREP is equivalent to the noise constant.}
5) _{Time from applying VS >= 3.0 V to the sensor until the output state is valid.}
6) _{Thermal resistance from junction to ambient.}
e.g.: V_S=12.0 V, R_S=100 Ohms, I_{Shigh_typ}=14 mA => Power Dissipation P_dis=148.4 mW.
In T_A = T_j – (R_thJA * P_dis) = 175 °C – (190 K/W * 0.1484 W) => T_A = 146.8 °C
