The ADA4571-2 is a 2-channel anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiersand ADC drivers. The device produces analog outputs that indicate the angular position of the surrounding magnetic field.
Each channel consists of two die within one package: an AMR sensor and a variable gain instrumentation amplifier. The ADA4571-2 delivers clean and amplified cosine and sine output signals per channel related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage.
Each sensing channel contains two separated wheatstone bridges at a relative angle of 45° to one another. A rotating magnetic field parallel to the plane of the IC package delivers two sinusoidal output signals, with the double frequency of the angle, α, between the sensor and the magnetic field direction. Within a homogeneous field parallel to the plane of the IC package, the output signals are independent of airgap between the sensor and the magnet.
The ADA4571-2 is available in a 16-lead SOIC package.
