AM256

Data sheet AM256D01_13 Issue 13, 22th May 2017 AM256 – angular magnetic encoder IC ® The AM256 is a compact solution for angular position sensing. 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 AM256 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 the magnetic field distribution. signals. The resolution of incremental ●● Contactless angular position output is selectable between 128 and encoding over 360° 256 counts per turn with an external pin. With its compact size the AM256 ●● Ideal for harsh environments due to magnetic sensing angular magnetic encoder is especially ●● Complete system-on-chip suitable for different applications, solution including motor motion control, ...
