MultiDimension Technology Co., Ltd. AMR Angle Sensor AMR3013P

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. SOP8 Features and Benefits Anisotropy of magnetoresistance (AMR) technology Wide airgap tolerance Compatible with wide range of supply voltages Excellent thermal stability Very low hysteresis Compact package RoHS and REACH compliant Applications Rotary position sensors Rotary encoders Contactless potentiometers Valve position sensors Knob position sensors
