Description: A1180 – A1184 Preliminary Data Sheet P RELIMINARY DATA SHEET SUBJECT TO CHANGE WITHOUT NOTICE Two-Wire, Programmable , Chopper-Stabilized, Unipolar Hall-Eff ect Switch The A118X is a two-wire, uni polar, Hall-effect switch family design ed for use in high-temperature applicat ions. This device uses a patented high frequency chopper-stabilization techniq ue on Allegro's new DABIC5 BiCMOS wafer fabrication process to achieve magneti c stability and to eliminate offset inh erent in single-element devices and fro m harshapplication environments. The A1 18X FAMILY of devices incorporates a pr ogrammability function to allow for ext ernal trimming of the operate point. Th e programming is performed after final
