The NVE AD824-00E precision digital magnetic sensor from NVE have a precision magnetic operate point of 28Oe (Typ.) with a frequency response of 0 to 100KHz and an excellent temperature and voltage perfomance. NVE’s AD Series of GMR switches are the industry standard for sensitivity and precision. These switches integrate GMR sensor elements with digital signal processing electronics, and are more precise than other magnetic sensors, with magnetic field operate points being stable over voltage and temperature extremes

  • Precision digital magnetic sensor
  • Digital NPN open-collector output
  • Supply voltage 4.5Vcc to 30Vcc
  • Supply current 1.75mA (Vcc=12V)
  • Output drive 2mA
  • Temperature and voltage stability
  • Short circuit protection (Vshort 0.17v max)
  • MSOP8 package
  • Frequency response to 100KHz

The AD824 sensor outputs turn ON when the magnetic field exceeds the 28 Oe operate point, and OFF when the field drops below 14 Oe. The output is “Omnipolar”, meaning the output will turn ON irrespective of the magnetic field polarity. Digital switching is achieved when the magnetic field passes across the axis of the IC. The AD824 outputs consist of two NPN open-collector current-sink and integrated short circuit protection. The open-collector outputs should have external pull-up and pull-down resistors. For microcontroller interfaces, the microcontroller’s input resistors can be activated.

Typical applications for the AD series include:

  • Motion, speed and position sensing
  • Pneumatic cylinder position sensing
  • Speed sensing
