Technical content
Datasheet V1.0a TMR2101 Large Dynamic Range TMR linear sensor General Description The TMR2101 linear sensor utilizes a unique push -pull half bridge composed of four unshielded TMR sensor elements. The unique bridge design provides a high sensitivity signal 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 TMR2101 is available in a 6 mm X 5 mm X1.7 mm 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
Weak Magnetic Field Sensing Current Sensors Displacement Sensing Rotary Position Sensors TMR2101 Transfer Curve The following figure shows the response of the TMR2101 to an applied magnetic field in the range of ± 30Oe (left) and ± 200 Oe (right) when the TMR2101 is biased at 1V. At low fields the TMR2101 response is highly linear, and it is not harmed when the sensor is driven into saturation.
