It is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique.

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 sensors is also available in the Allegro Electronic Data Book AMS-702 or Application Note 27701, or www.allegromicro.com
