NVE AHT925-14E

NVE AHT925-14E

The revolutionary AHT925-14E 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 AHT925-14E digital switches are available in an ultraminiature leadless ULLGA package size 1.1x1.1mm.

  • Low voltage, nanopower TMR digital switch
  • Omnipolar magnetic switch with output turning on when magnetic field is applied
  • 0.9 - 1.8V operating voltage for single-cell operation
  • Quiescent current as low as 1μA typical
  • Continuous operation for low noise and high speed
  • Operate points offering sensitivity as low as 1.5mT, and stability over supply voltage and temperature
  • Operating temperature range of −40°C to +85°C

Typical applications for the AHT series include:

  • Single-cell battery or harvested power applications
  • Gas and water meters
