MDT Multidimensional Technology AMR3005 dual-axis AMR angle sensor

Introduction

AMR3005 is sensor chip based on the AMR effect,which can measure the of the external magnetic field. AMR3005 contains two unique push-pull Wheatstone bridges. The output voltages of the two Wheatstone bridges are proportional to the sine and cosine of twice the magnetic field,that is,proportional to sin(2θ) and cos(2θ),θ is The of the magnetic field. The AMR3005 works in a saturated field and has strong resistance to external magnetic field interference; each Wheatstone bridge in the AMR3005 contains four high-sensitivity AMR sensing elements. This bridge structure can effectively compensate for the temperature drift of the sensor; in addition,the AMR3005 Adopting LGA package,it has the characteristics of small package size and convenient assembly.
