5 Electrical and Magnetic Parameters
Calculation of the ambient temperature (SC59 example)
e.g. for VS = 12.0 V, IStyp = 4 mA, VQSATtyp = 0.3 V and IQ = 20 mA :
Power Dissipation: PDIS = 54.0 mW.
In TA = Tj – (RthJA × PDIS) = 175°C – (100 K / W × 0.054 W )
Resulting max. ambient temperature: TA = 169.6°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 - 3 dB corner frequency of the low pass filter in the signal path.
