Symmetry Sensitivity Error
A136x device is constant for any two applied magnetic fields of
equal magnitude and opposite polarities.
Symmetry error, Sym

Note that the symmetry error specification is only valid for bipolar
devices.
Ratiometry Error
This means that the quiescent voltage output, V
sensitivity, Sens, and clamp voltage, V
are proportional to the supply voltage, V
the supply voltage increases or decreases by a certain percent-
age, each characteristic also increases or decreases by the same
percentage. Error is the difference between the measured change
