A1245 Description
The A1245 is a two-wire Hall-effect latch. The device is produced on the Allegro™ advanced BiCMOS wafer fabrication process, which implements a high frequency, 4-phase, chopperstabilization 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.
