General Description

The TMR2905 linear sensor utilizes a unique push-pull Wheatstone bridge composed of four unshielded TMR sensor elements.

The unique bridge design provides a high sensitivity differential output that is linearly proportional to a magnetic field applied

parallel to the surface of the sensor package, and it provides superior temperature compensation of the output. The TMR2905 is

packaged in 6mm X 5mm X 1.5mm SOP8 named TMR2905P, and packaged in3mmX3mmX0.75mm DFN8 named TMR2905D.
