AMR Angle Sensor AMR3013P AMR3013P AMR Angle Sensor Features and Benefits       Anisotropy of magnetoresistance (AMR) Technology Compatible with Wide Range of Supply Voltages Wide Airgap Tolerance Excellent Thermal Stability Very Low Hysteresis Compact Package Applications      Rotary Position Sensors Rotary Encoders Contactless Potentiometers Valve Position Sensors Knob Position Sensors General Description The output voltage of the AMR3013P AMR angle sensor is proportional to the sine or cosine functions of two times of the angle – sin(2α) and cos(2α) – of a magnetic field applied parallel to the surface of the sensor, which can be provided by a small magnet positioned above the device. The AMR3013P includes two Wheatstone bridges, which can be configured to output sine and cosine functions respectively. Each bridge includes four AMR sensor elements in a push-pull arrangement to produce a peak-to-peak signal at 2.6% of the supply voltage. Additionally, the unique AMR Wheatstone bridge technology accurately compensates the output against changes in ambient temperature. This sensor is assembled in a compact SOP8 package Operation A small magnet, placed above the AMR3013P, can be used to provide a magnetic field in any desired orientation parallel to the plane of the AMR3013P package. The following chart show a typical sensor output as a function of the angle within 0~180 of the applied magnetic field using a 6 mm diameter, 2.5 mm thick magnet and at 1 V supply.
