AH8502-FDC-7

AH8502-FDC-7 is a micropower linear hall-effect sensor with an 8-bit output resolution. The output voltage is ratiometric to the supply voltage and proportional to the magnetic flux density, perpendicular to the part marking surface. The output null voltage is at half the supply voltage. Designed for battery-powered consumer equipment, office equipment, home appliances, and industrial applications, the AH8502 can operate over the supply range of 1.6V to 3.6V. The device has a CNTRL pin to select operating modes and sampling rate, minimizing power consumption. Applications include level, proximity, position and travel detection, button press detection in digital still, video cameras and handheld gaming consoles, position detection in door, lids, and trays, liquid level detection, joy stick control – gaming and industrial applications, smart meters, contact-less level, proximity and position measurement in home appliances and industrial applications.
