Ratiometric Linear Hall Effect Sensor With Analog Output For Compact Magnetic Field And Position Sensing Applications
The MT9105ET is a ratiometric linear Hall-effect sensor designed to provide a precise analog output proportional to the strength and polarity of an applied magnetic field. Its compact SOT-23-3 package makes it ideal for space-constrained electronic designs requiring accurate magnetic field measurement, position sensing, displacement detection, and contactless control. The sensor delivers a linear output characteristic that enables smooth and reliable magnetic field monitoring in industrial, consumer, and portable electronic applications.
The ratiometric output architecture improves measurement accuracy by scaling the output voltage with the supply voltage, making the device particularly suitable for systems that use the same supply voltage as the ADC reference. The solid-state Hall-effect sensing technology eliminates mechanical wear and provides long-term reliability, while the compact surface-mount package simplifies integration into modern high-density PCB designs.
