Allegro Microsystems A3250/A3251 Hall-Effect Switches Datasheet
The document describes the A3250 and A3251, which are field-programmable, chopper-stabilized, unipolar Hall-effect switches. These devices utilize a chopper-stabilization technique to eliminate offset inherent in single-element devices, ensuring stable switchpoints throughout the operating temperature range.
