General Description:The MultiDimension TMR9112 Tunneling Magnetoresistive(TMR) sensors are magnetoresistive Wheatstone bridges configured to measure magnetic fields reliably after exposure to large magnetic field or experiencing extreme temperature drift,which can be powered using a voltage or current supply.When power is applied,the magnetoresistive Wheatstone bridge converts any magnetic field applied along the sensing axis direction to a differential output voltage.In addition to the magnetoresistive bridge circuit,the TMR9112 also includes an initialization coil that is magnetically coupled to the TMR sensor.This MultiDimension patented feature permits proper magnetic domain alignment, even in an uncontrolled environment where large magnetic field exposure or temperature change is unavoidable,resulting in a sensor that can provide stable low hysteresis and low offset output.The TMR9112 is assembled in a 6mm X 6 mm X 0.75 mm LGA package.


Features and Benefits:(1)Tunneling Magnetoresistance(TMR)Technology;(2)Ultra High Sensitivity (~1000mV/V/Oe);(3)Ultra Low Noise Spectral Density (150pT/√Hz@1Hz);(4)Very Low Power Consumption;(5)Excellent Thermal Stability,Small Offset;(6)Low Hysteresis;(7)Compatible with Wide Range of Supply Voltages;(8)Initialization Coil for Accurate Operation After High Magnetic Field Exposure


Applications:(1)Weak Magnetic Field Sensing;(2)Current Sensors;(3)Position and Displacement Sensing;(4)Bio-medical Sensing;(5)Magnetic Communication;(6)Precision Sensing in Uncontrolled Magnetic Environments.
