¹Additional information on chracteristics is provided in the section Characteristics Deﬁnitions, on the next page.

²Negative current is deﬁned as conventional current coming out of (sourced from) the speciﬁed device terminal.

³Typical data is at T_A= 25°C, except for ΔSens, and at x.x Sens. Typical data are for initial design estimations only, and assume optimum

manufacturing and application conditions. Performance may vary for individual units, within the speciﬁed maximum and minimum limits.

In addition, the typical values vary with gain.

⁴10 G = 1 millitesla.

⁵After 150ºC pre-bake and factory programming.

⁶Sensitivity drift is the amount of recovery with time.
