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 signa l 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 ambi ent temperature. This sensor is

assembled in a compact LGA8 package of 3.0 mm × 3.0 mm × 0.75 mm.
