The A3282 Hall-effect sensor is a temperature stable, stress-resistant latch. 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. The A3282 complements the current Allegro family of chopper-stabilized latching sensors.
