Quiescent Voltage Output:
With no magnetic field present the device is in the quiescent state
and the voltage output is approximately equal to one-half the supply voltage (V
OQ
V
CC
/2) over
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.
Sensitivity:
A magnetic south pole at and perpendicular to the device’s symbolized package
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 in sensitivity over temperature is specified in percent by the calculation
Ratiometry:
The quiescent voltage output and sensitivity of these ratiometric linear Hall effect
devices are proportional to the supply voltage. The change in quiescent voltage output with
supply voltage is specified in percent by the calculation.
The change in sensitivity with supply voltage is also specified in percent by the calculation
Linearity and Symmetry:
The ability of the voltage output to vary in constant proportion to the
applied magnetic field is linearity and is specified in percent by the calculation
The output symmetry is also specified in percent by the calculation
