A1126LLHLX-T

The A1126LLHLX-T is a chopper-stabilized omnipolar Hall Effect Switch with a digital output. The device includes voltage regulator, hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger and a short-circuit-protected open-drain output. Advanced BiCMOS wafer fabrication processing is used to take advantage of low-voltage requirements, component matching, very low input-offset errors. This device is especially suited for operation through extended temperature ranges, up to 150°C. Superior high-temperature performance is made possible through an Allegro™ patented dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-moulding, temperature excursions and thermal stress.
