Data Sheet
@ V
In the lowest programmable sensitivity range a sensitivity less or equal to min(S) is guaranteed.
In the highest programmable sensitivity range a sensitivity of greater or equal to max(S) is guaranteed.

The temperature coefficient of the magnetic sensitivity is the slope of a linear least-square fit through
the real curve.
For lower sensitivities, the zero voltage drift is dominant (see
Equivalent to magnetic input noise at 25 °C. The equivalent magnetic input noise depends on the selected
sensitivity. At highest sensitivity it is typically 25 µT
