Characteristics Definitions
Quiescent voltage Output: With no magnetic field present the device in the quiescent state and the voltage
Linearity & Symmetry: The ability of the voltage output to vary in constant proportion to the applied
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Ratiometry: The quiescent voltage output and sensitivity of these ratiometric linear Hall-effect
Sensitivity: A magnetic south pole at, and perpendicular to, the device’s symbolized package
output is approximately equal to one-half the supply voltage (V
the operating voltage and temperature range. The change in quiescent voltage
output over temperature gives the device’s equivalent accuracy and is specified in
gauss by the calculation.
face will increase the voltage output above the quiescent value. Conversely a
magnetic north pole will decrease the voltage output below the quiescent value.
This change in voltage output with applied magnetic field is sensitivity and is
specified in mV/G by the calculation.
The change is sensitivity over temperature is specified in percent by the
calculation
devices are proportional to the supply voltage. The change in quiescent voltage
output with supply voltage is specified in percent by the calculation
This change in sensitivity with supply voltage is also specified in percent by the
calculation
magnetic field is linearity and is specified in percent by the calculation
The output is also specified in percent by the calculation
