A3230 Overview
The A3230 Hall-effect sensor is a temperature stable, stressresistant bipolar switch. This sensor is the most sensitive Hall-effect device in the Allegro® bipolar switch family and is intended for ring-magnet sensing. Superior high-temperature performance is made possible through an Allegro patented dynamic offset cancellation that utilizes chopper-stabilization.
