A1244 Description
The A1244 is a two-wire Hall-effect latch. The devices are produced on theAllegro™ advanced BiCMOS wafer fabrication process, which implements a 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.
