A1128 Datasheet (Allegro) - Highly Programmable Hall-Effect Switch

A1128, Highly Programmable Hall-Effect Switch

The A1128 is a field-programmable, unipolar Hall-effect switch designed for use in high-temperature applications.

This device uses a chopper-stabilization technique to eliminate offset inherent in single-element devices.

The devices are externally programmable.

A wide range of programmability is ava
