Description
●The A1244 is a two-wire Hall-effect latch. The devices are produced on the Allegro™advanced BiCMOS wafer fabrication process, which implements a patented high frequency, 4-phase, chopper-stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.
●Features and Benefits
