Overview
Not recommended for new design.
The IC senses the angular position of a permanent magnet placed above the chip. The permanent magnet must be diametrically polarized and of cylindrical shape.
The AM512B uses Hall sensor technology to detect the magnetic flux density distribution at the surface of the silicon. Hall sensors are placed in a circular array around the center of the IC and deliver a voltage representation of magnetic field distribution.
Features
