Foot Controller Reference Design using Analog Hall Sensor

TIDA-00642

Design files

Overview

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.

Features
  • 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

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
