Description
The A1126 integrated circuit is an omnipolar, ultrasensitive Hall-effect switch with a digital output. This device has an integrated regulator permitting operation to 24 V.
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 overmolding, temperature excursions, and thermal stress.
