Product Description
Product Overview
The MT910X is a ratiometric linear Hall-effect IC with an analog output, designed for accurate position sensing in a wide range of applications. It operates from a 3.0V to 5.5V power supply and provides a linear output proportional to magnetic flux density. The device offers four sensitivity options to maximize output voltage swing based on the required sensing range. North and south magnetic poles produce unique voltages. Available in SOT-23 (Thin Outline) for surface mount and flat TO-92 for through-hole mount, all packages are RoHS compliant.
