The bias generator provides currents for the Hall probes and the active circuits. Compensation circuits stabilize the temperature behavior and reduce technology variations. The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall probes caused by molding and soldering processes and other thermal stresses in the package. This chopper technique together with the threshold generator and the comparator ensures high accurate magnetic switching points.

Typical values correspond to VS = 12 V and TA = 25°C 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. Systematic delay between magnetic threshold reached and output switching Jitter is the unpredictable deviation of the output switching delay BREP is equivalent to the noise constant Time from applying VS ≥ 2.7 V to the sensor until the output state is valid Thermal resistance from junction to ambient Calculation of the ambient temperature: e.g. for VS = 12.0 V, IStyp = 5.5 mA, VQSATtyp = 0.3 V and 2 x IQ = 10 mA : Power Dissipation: PDIS = 72.0 mW.
