Zero-drift Hall-effect current sensors

Achieve consistent, accurate measurements over time and temperature

Our Hall-effect current sensors provide the industry’s highest accuracy combined with the lowest drift, enabling consistent, accurate current measurements over both time and temperature.  Additionally, our Hall-effect current sensors offer higher isolation voltage levels than the competition for equivalent packages.

Low drift

Zero-drift architecture and real-time sensitivity compensation correct for changing temperature, package stress and aging, enabling the industry’s lowest drift over time and temperature.

  • Low sensitivity temperature
  • Low lifetime sensitivity drift
  • Low offset drift

High accuracy

Increase overall system performance with higher efficiency, safer systems and tighter system control

  • Full-scale error < 1%
  • Linearity error < 0.1%


Exceeds industry regulations to meet demanding environmental and use-case conditions with high working voltage extends product lifetime

  • 600-V working voltage
  • 3-kVrms dielectric withstand isolation
  • UL1577 standard
