Allegro MicroSystems ATS617LSG: Differential Hall-effect sensor uses peak-detecting algorithm

The three-wire ATS617LSG differential analog Hall-effect sensor switches in response to changing magnetic fields. The dynamic, peak-detecting sensor uses an analog peak-detecting algorithm, automatic gain control, and an integrated tracking capacitor, providing accurate edge detection corresponding to a rotating ferrous target. The peak-detecting algorithm suits use in camshaft systems that can sense a range of target geometries, including fine-pitch, encoded targets. The ATS617LSG differential Hall-effect sensor costs $2.55.
