Operation with Fine-Pitch Ring Magnets
cular pitch of less than 4 mm, a performance improvement can be
observed by rotating the front face of the device (see below). This
rotation decreases the effective Hall element-to-element spacing,
provided that the Hall elements are not rotated beyond the width
of the target.
Applications
0.01 μF bypass capacitor be connected (in close proximity to the
device) 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 applications information on magnets and
Hall-effect sensor ICs is also available in the “Hall-Effect IC
Applications Guide” which can be found in the latest issue of
Application Note 27701, at www.allegromicro.com/techpub2/an/
