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.
