Programmable Linear Hall Effect Sensor
3 Glossary of Terms
mT (milli-Tesla) = Unit of measurement for magnetic flux density. 1mT is equal to 10 Gauss.
V_OQ (Output Quiescent Voltage) = Output voltage at zero magnetic field, V_OUT for B = 0 mT.
Sensitivity = Change in output voltage versus change in magnetic field. ∆ V_OUT / ∆ 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.
