Key Document


This reference design includes an analog Hall sensor and an OpAmp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of magnet and Hall sensor are analysised. Adjustable offset and system gain are provided along with the OpAmp circuit to achieve desired output bias and range.

  • Approximate linear response
  • Adapt to wide magnet types and field range
  • 0 to 5V full scale output ability
  • Adjustable quiescent offset and gain
  • Low power RRIO amplifier stage
  • Cost-effective
