Product Description The device is a linear Hall effect IC that responds proportionally to magnetic flux density. The device can be used for accurate position sensing in a wide range of applications.

1 Product Description The device is a linear Hall effect IC that responds proportionally to magnetic flux density. The device can be used for accurate position sensing in a wide range of applications. The device operates from.0v to 5.5V power supplies. When no magnetic field is present, the analog output drives ½ of VCC. The output changes linearly with the applied magnetic flux density, and four sensitivity options enable maximal output voltage swing based on the required sensing range. North and south magnetic poles produce unique voltages. The family provides a variety of packages to customers. (Thin Outline) for surface mount and flat TO-9 for through-hole mount. All packages are RoHS compliant.
