Application schematics of AMR4100

Description

AMR4100 is based on the principle of anisotropic

magnetoresistance (AMR), and its output voltage

changes with the direction of the magnetic field

(target magnetic field) received. The AMR4100

outputs two sets of analog voltage signals (sine and

cosine) with a phase difference of 45° when the

magnetic field direction rotates one circle. The period

of these two sets of analog voltage signals is twice

the rotation period of the magnetic field direction.

The angular position information of the target magnetic

field can be determined in real time by calculating

the two sets of analog voltage signals.

Through the optimized design, the temperature drift

of the AMR4100 is effectively compensated, the

measurement accuracy of the sensor in various

application environments is improved, and the

limitation for the installation distance between the

measured object and the sensor is reduced. It is

available in the compact DFN12L(6 mm × 2 mm ×

0.75 mm) packages and easy to assemble in tight

spaces.
