A1250 Overview
The A1250 Hall-effect sensor IC is a temperature-stable, stress-resistant bipolar switch. This device 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 dynamic offset cancellation that utilizes chopper stabilization.
