Dual Axis AMR Magnetic Angle Sensor AMR3003
Description
The AMR3003 is a magnetic angle sensor based on anisotropic magnetoresistance (AMR) technology. It senses the magnetic field parallel to the surface of the sensor with the range of magnetic field rotation angle θ from 0° to 180°, and outputs voltage proportional to the sine or cosine of 2θ. The AMR3003 adopts two push-pull Wheatstone bridges design, and each bridge contains four high-sensitivity AMR sensing elements to provide output signal as large as 1.6% of the supply voltage. Additionally, this unique AMR Wheatstone bridge design effectively compensates the output against changes in ambient temperature. It is available in LGA8L (5 mm x 5 mm x 0.9 mm) and DNF6L (2 mm x 3 mm x 0.75 mm) packages. Features and Benefits
