General Description
The output voltages of the dual-axis TMR3004 TMR high-field angle sensor are proportional to the sine and cosine of the angle of a magnetic field applied parallel to the surface of the TMR3004.These sine and cosine signals are provided by two orthogonal full bridge TMR angle sensors. Each full bridge TMR angle sensor includes four unique high-field TMR sensor arms connected in a push-pull arrangement to produce a best-in-class peak-to-peak signal as large as 90% of the supply voltage, eliminating the need for amplification in many applications, while maintaining low error as the magnetic field is varied over a range of 1 kOe. Additionally, the TMR full bridge technology accurately compensates the output against changes in ambient temperature. This sensor is assembled in a compact LGA8 package of 3.0 mm × 3.0 mm × 0.9 mm.
