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.
