1) Output DAC full scale = 5 V ratiometric, Output DAC offset = 0 V, Output DAC LSB = V

SUP/4096

2) If more than 50% of the selected magnetic field range is used and the temperature compensation is suitable.

INL = VOUT - VOUTLSF with VOUTLSF = Least Square Fit through measured output voltage

3) Signal Band Area with full accuracy is located between V

OUTL and VOUTH. The sensor accuracy is reduced below VOUTL

and above VOUTH

4) External package stress or overmolding might change this parameter

5) Guaranteed by Design

6) Characterized on small sample size, not tested
