The voltage signal output by the two axes of the chip has a sine and cosine relationship with the angle of the magnetic field, when a magnet is placed above the TMR3005 chip to provide an operating magnetic field parallel to the surface of the chip in general angle sensor application. Additionally, the TMR full bridge technology accurately compensates the output against changes in ambient temperature. This high performance TMR3005 angle sensor is available in packaging form factors of compact LGA8L (3 mm × 3 mm × 0.75 mm).
