NVE AHT925-01

  • NVE

Product Features

  • Low voltage, nanopower TMR digital switch
  • In-plane direction of sensitivity
  • Omnipolar – output is activated if magnetic field of either polarity is applied
  • Continuous operation for low noise and high-speed
  • Ultrasensitive operate point, as low as 1.5mT

Applications

  • Compliant

The revolutionary AHT925-01 TMR magnetic digital switch from NVE combines low voltage, nanopower and high speed, designed for continuous operation for low noise and high speed applications. It utilises Tunneling Magnetoresonance (TMR) technology and features low supply voltage of 0.9 – 1.8V for single-cell operation, the lowest quiescent current available in a continuous-duty solid state magnetic switch of 1μA typical and sensitive and extremely stable operate points as low as 1.5mT. These sensor devices have the output configured as a “switch” – the output turns on when the magnetic field of any polarity is applied and turned off when the magnetic field is removed. The AHT925-01 digital switches are available in a bare die form size 0.6×0.6mm.
