AH8501-FDC-7

AH8501-FDC-7 is a high-accuracy, low-power/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. Designed for battery-powered consumer equipment to office equipment, home appliances and industrial applications, the AH8501 can operate over the supply range of 1.6V to 3.6V and uses an externally controlled ENABLE pin clocking system to control operating modes and sampling rates and to minimize power consumption. Applications include high accuracy level, proximity, position and travel detection, button press detection in digital still, video cameras and handheld gaming consoles, accurate door, lids and tray position detection, liquid level detection, joystick control – gaming and industrial applications, contact-less level, proximity and position measurement in home appliances and industrial applications.
