Explanation
Unit of measurement for magnetic flux density. 1mT is equal to 10 Gauss.
Output voltage at zero magnetic field, V_OUT for B = 0 mT.
Change in output voltage versus change in magnetic field (∆ V_OUT / ∆ B)
Change in Sensitivity over temperature.
Listed in units of ppm / °C (where 100ppm / °C. = 0.01% / °C)
Melexis in-circuit programming protocol.
