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 >= 2.7 V to the sensor until the output state is valid.

6) Thermal resistance from junction to ambient.

e.g.: VS=12.0 V, IS_typ=4 mA, VQSAT_typ=0.3 V, IQ=20 mA => Power Dissipation Pdis=54.0 mW.

In TA = Tj – (RthJA * Pdis) = 175 °C – (100 K/W * 0.054 W) => TA = 169.6 °C
