3 Glossary of Terms
Term Explanation
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
/ ∆ B)
TempCo (Sensitivity
Temperature Compensation)
Change in Sensitivity over temperature.
Listed in units of ppm / °C (where 100ppm / °C. = 0.01% / °C)
PTC (Programming Through
the Connector)
Melexis in-circuit programming protocol.
MSB Most Significant Bit.
LSB Least Significant Bit.
