Description
The A3230 Hall-effect sensor is a temperature stable, stress resistant 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. This method reduces the offset voltage normally caused by device overmolding, temperature dependencies, and thermal
stress.
