Technical content
Datasheet V1.0a TMR2701 High Sensitivity and Low Hysteresis TMR linear sensor General Description The TMR2701 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 ap plied parallel to the surface of the sensor package, and it provides superior temperature compensation of the output. The TMR2701 is available a 6mm X 5mm X 1.5mm SOP8 package. Features and Benefits Tunneling Magneto resistance (TMR) Technology High Sensitivity Large Dynamic Range Very Low Power Consumption Excellent Thermal Stability Very Low Hysteresis Compatible with wide Range of Supply Voltages
Applications
