Product Overview

The A1126 is an omnipolar, ultrasensitive Hall-effect switch with a digital output, designed for operation up to 24V and extended temperature ranges up to 150C. It features dynamic offset cancellation for superior high-temperature performance, making it insensitive to physical stress and temperature excursions. The device integrates a voltage regulator, Hall-voltage generator, amplifier, chopper stabilization, Schmitt trigger, and a short-circuit-protected open-drain output. Its omnipolar operation allows activation by either north or south magnetic polarity, simplifying manufacturing by eliminating the need for precise magnet orientation. This makes it an excellent replacement for reed switches in industrial, consumer, and automotive applications.
