... A3340 Chopper-Stabilized, Precision Hall-Effect Switch Chopper-Stabilized Technique. The Hall element can be considered as a resistor array similar to a Wheatstone bridge. A large portion of the offset is a result of the mismatching of these resistors. These devices use a proprietary dynamic offset cancel- lation technique, with an internal high-frequency clock to reduce ...
