General Description

The A3241 and A3242 integrated circuits are unipolar Halleffect switches with digital outputs.

These devices are suited for operation over extended temperature ranges, up to +150°C.

Superior high-temperature performance is made possible through an Allegro® dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.

Overview
