General Description

The TMR9003 linear sensor utilizes a unique push-pull Wheatstone bridge composed of

four 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 TMR9003 is

assembled in a 6mm  5mm  1.5mm SOP8 package.

Transfer Curve

The following figure shows the response of the TMR9003 to an applied magnetic field in the

range of ±5 Oe and ±40 Oe when the TMR9003 is biased at 1 V. The following specifications are

calculated over an analysis range of ±5 Oe.
