General Description
The TMR2922 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 TMR2922 is
available a 6mm 5mm 1.5mm SOP8 package.

Transfer Curve
The following figure shows the response of the TMR2922 to an applied magnetic field in the
range of ±15 Oe when the TMR2922 is biased at 1 V.
