A1181 - Unipolar Hall-Effect Switch

Download the A1181 datasheet PDF. This datasheet also covers the A1180 variant, as both devices belong to the same unipolar hall-effect switch family and are provided as variant models within a single manufacturer datasheet.

Description

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.

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.
