AH8115 is higher sensitivity of magnetic induction than ah8113, it can be used in security systems sensing magnet smaller occasions. the AH8115 is available in tsot- 23, package. orderi ng i nfor m a tion p ac k ag e ty pe p art n um be r tsot- 23 te3 AH8115te3r AH8115te3vr note v: halogen free package r: tape & reel ait provides all rohs products suffix v means halogen free package ? micro power design ? 2.0v to 5.5v battery operation ? high sensitivity and high stability of the magnetic switching points ? high resistance to mechanical stress ? digital output signal ? switching for both poles of a magnet (omnipolar) ? not suitable for automotive application ? operating temperature range ? t min t a t max ?40c t a 85c ? operating voltage range 2.0v v dd 6.0v ? available in tsot- 23 package a p p l icati on ? mobile phones ? notebook ? portable electronic devices typ ical a p p l icati on
