“AKM electronic compass ICs uses magnetic sensors (Hall element) with wide dynamic range and ideal linearity. The silicon monolithic structure achieves high accuracy and reliability, and it is optimized for high-volume manufacturing.”
Semiconductor magnetoresistive element (SMRE)
“Since a Sn doped single crystal film InSb is used as a material for the sensing element, the element has excellent magnetoresistive temperature characteristics and very small neutral voltage temperature drift. This element is mainly used for detection of gear rotation.”
Principle of operation of Hall effect IC
Detects a magnetic field and output analog/digital(IC) signal proportional to the intensity of the magnetic field. used for non-contact type switches, rotation detection, and position detection. The Hall effect IC consists of Hall element and signal conditioning circuitry to convert the Hall element output into a digital output.
