Product Description
Product Overview
The MT910X is a ratiometric linear Hall-effect IC with an analog output, designed for accurate position sensing. It operates from a 3.0V to 5.5V power supply, with the analog output at half of VCC when no magnetic field is present. The output voltage changes linearly with applied magnetic flux density. Four sensitivity options are available to optimize output voltage swing for various sensing ranges. The device is available in SOT-23 (Thin Outline) for surface mount and flat TO-92 for through-hole mount packages, both RoHS compliant.
