Extensive applications information for Hall-effect sensors is available in:

• Hall-Effect IC Applications Guide, Application Note 27701;

• Hall-Effect Devices: Soldering, Gluing, Potting, Encapsulating, and Lead Forming, Application Note 27703.1;

• Soldering of Through-Hole Hall-Sensor Dervices, Application Note 27703; and

• Soldering of Surface-Mount Hall-Sensor Devices, Application Note 27703.2.

More detailed descriptions of the chopper-stabilized circuit operation can be found in:

• Monolithic Magnetic Hall Sensor Using Dynamic Quadrature Offset Cancelation, Technical Paper STP 97-10; and

• Chopper-Stabilized Amplifiers With A Track-and-Hold Signal Demodulator, Technical Paper STP 99-1.

It is strongly recommended that an external bypass capaci-

tor 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 tech-

nique.
