The Hall effect, discovered by E. H. Hall in 1879, is the
basis for all Hall-effect devices. When this physical effect
is combined with modern integrated circuit (IC) technology,
many useful magnetic sensing products are possible. The
Hall element, when properly biased, produces an output
voltage that is proportional to a magnetic field. This small
voltage is processed through a high-quality amplifier, which
produces an analog signal that is proportional to the applied
flux density. In Allegro? Hall-effect devices, the signal
is conditioned and optimized for various types of outputs
indicating magnetic flux conditions
