1. Introduction
Analog Hall sensor can be used as position or angular sensing with the benefits of no contact and
wearing, high stability and repeat positioning accuracy and wide sensibility range. There are normally
two major methods of the configuration of the magnet and the Hall senor, non-linear and linear way.
This design gives introduction of the two methods and focuses on the linear configuration, and gives
OpAmp circuit design to achieve wide adaption to different applications.
