Overview
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 devices and from harshapplication environments.
The A118X FAMILY of devices incorporates a programmability function to allow for external trimming of the operate point.
The programming is performed after final packaging of the sensor and placement of the Single In-Line Package (SIP) into the application.
This advanced feature allows for optimization of sensor switching performance by effectively accounting for variations caused by magnet and SIP placement tolerances.
These devices provide on-chip transie...
