General Description
The AS1247 is small, versatile linear Hall effect
devices which are operated by the magnetic field from
a permanent magnet or an electromagnet. They are
optimized to accurately provide a voltage output that is
proportional to an applied magnetic field. These
devices have a quiescent output voltage that is about
50% of the supply voltage
