A1181 Unipolar Hall-Effect Switch

Chopper-Stabilization Technique. A limiting factor for switch point accuracy when using Hall effect technology is the small signal voltage developed across the Hall plate. This voltage is proportionally small relative to the offset that can be produced at the output of the Hall sensor. This makes it.

A1180 A1184 Preliminary Data Sheet PRELIMINARY DATA SHEET SUBJECT TO CHANGE WITHOUT NOTICE Two-Wire, Programmable, Chopper-Stabilized, Unipolar Hall-Effect Switch The A118X is a two-wire, unipolar, Hall-effect switch family designed for use in high-temperature applications. This device uses a patented high frequency chopper-stabilization technique on Allegro's new DABIC5 BiCMOS wafer fabrication process to achieve magnetic stability and to eliminate offset inherent in single-element d.
