1) over operating range, unless otherwise specified. Typical values correspond to VS = 12V and TA = 25°C

2) 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

3) Systematic delay between magnetic threshold reached and output switching

4) Jitter is the unpredictable deviation of the output switching delay

5) Time from applying VS ≥ 3.0V to the sensor until the output state is valid

6) Thermal resistance from junction to ambient

Calculation of the ambient temperature:

e.g. for VS = 12.0V, RS = 100W, ISHIGHtyp = 14mA :

Power Dissipation: PDIS = 148.4mW.

In TA = Tj – (RthJA x PDIS) = 175°C – (100K/W x 0.15W)

Resulting max. ambient temperature: TA = 160°C
