Applications Information
Operation with Fine-Pitch Ring Magnets. For
targets with a circular pitch of less than 4mm, a perfor-
mance improvement can be observed by rotating the front
face of the device (see below). This device rotation
decreases the effective element-to-element spacing,
provided that the Hall elements are not rotated beyond the
width of the target.
Applications.  It is strongly recommended that an
external 0.01 礔 bypass capacitor be connected (in close
proximity to the Hall elements) between the supply and
ground of the device to reduce both external noise and
noise generated by the internal logic.
The simplest form of magnet that will operate these
devices is a ring magnet. Other methods of operation,
such as linear magnets, are possible. Extensive applica-
tions information on magnets and Hall-effect devices is
also available in the Hsall-Effect IC Applications Guide
which can be found in the latest issue of the Allegro
MicroSystems Electronic Data Book, AMS-702 or Appli-
cation Note 27701, or at
