Description
The AMR3008 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 AMR3008 adopts two push-pull Wheatstone
bridges design, and each bridge contains four
high-sensitivity AMR sensing elements to provide
output signal as large as 1.3% 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.
