The AAT001-10E angle sensor is a unique array of four Tunneling Magnetoresistance (TMR) elements
rotated at 90 degree intervals in the package and connected in a bridge configuration. The output can be
configured to represent the sine and cosine functions of the magnetic field applied to the sensor. Each TMR
sensor element has a resistance of approximately 1.25 megaohms. Outputs are proportional to the supply
voltage and peak-to-peak output voltages are much larger than other sensor technologies. The part is
packaged in NVE’s 2.5 mm x 2.5 mm x 0.8 mm TDFN6 surface mount package.
Each sensor elements contain two magnetic layers: a “pinned,” or fixed direction layer; and a movable-
direction, or “free” layer. The diagram below illustrates the configuration, using arrows to represent the two
