Principles
The quiescent output voltage (B=0mT) is
nominally one-half the supply voltage. When a south magnetic pole
presented to the branded face of the Hall-effect IC, it will drive
the output higher than the quiescent voltage. A north magnetic pole
will drive the output below the quiescent output voltage.
In operation, instantaneous and proportional output voltage levels
are dependent on magnetic flux density at the most sensitive area of
the device. Greatest sensitivity is obtained with a supply voltage
of 6V, but at the cost of increased supply current and a slight loss
of output symmetry. The IC output is usually capacitively coupled
to an amplifier that boosts the output above the millivolt level.
Note:
Mechanical stress should be lessened as
far as possible in the process of assembly.
The soldering temperature at the leads should be less than 260°C
with 5 seconds. If N pole is approaching Hall-effect ICs from the
back side of the package, output voltage will increase, S pole is
approaching ICs from the back side, output voltage will reduce; and
if from the branded side of the package, the output situation is
just to the contrary.
