1) _{Valid for VOUT in the range from 10% to 90% VDD.}
2) _{Not for the -E6782 version.}
3) _{@ 25 °C}
4) _{For Sensitivity S < 80 mV/mT, for higher sensitivities the zero field drift is dominant (see Table 5).}
5) _{Definition: Rat = (VOUT(VDD) / VDD) / (VOUT (VDD = 5 V) / 5 V) x 100%}
for V_out in the range from 10% V_DD to 90% V_DD.
6) _{The output voltage has reached 99% of its final value within tPon after power on.}
7) _{No external filtering, with a sensitivity of 30 mV/mT (digital switching noise included) @ 25 °C.}
