3425 Datasheet (Allegro MicroSystems) - DUAL/ CHOPPER-STABILIZED/ ULTRA-SENSITIVE/ BIPOLAR HALL-EFFECT SWITCH

3425, DUAL/ CHOPPER-STABILIZED/ ULTRA-SENSITIVE/ BIPOLAR HALL-EFFECT SWITCH

Chopper-Stabilized Technique.

These devices use a proprietary dynamic offset cancellation technique, with an internal high-frequency clock to reduce the residual offset voltage of the Hall element that is normally caused by device overmolding, temperature dependencies, and thermal stress.

This techn

3425 DUAL, CHOPPER-STABILIZED, ULTRA-SENSITIVE, BIPOLAR HALL-EFFECT SWITCH The A3425LK dual Hall-effect switch is an extremely temperature-stable and stress-resistant sensor especially suited for use in digital-encoder systems in the harsh environments of automotive or industrial applications over extended temperature ranges to +150°C.

Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device o
