A1244 Datasheet - Allegro MicroSystems

A1244 Two Wire Hall-Effect Latch

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 elimina.
