3 Glossary of Terms

mT (milli-Tesla) = Unit of measurement for magnetic flux density. 1mT is equal to 10 Gauss.

VOQ (Output Quiescent Voltage) = Output voltage at zero magnetic field, VOUT for B = 0 mT.

Sensitivity = Change in output voltage versus change in magnetic field, ∆ VOUT / ∆ B.

TempCo (Sensitivity Temperature Compensation) = Change in Sensitivity over temperature. Listed

in units of ppm / °C (100ppm / °C. = 0.01 % / °C.).

PTC (Programming Through the Connector) = Melexis in circuit programming protocol.

MSB = Most Significant Bit.

LSB = Least Significant Bit.
