TMR9001

Datasheet V1.0a TMR2922 Ultra High Sensitivity TMR linear sensor 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 X 5mm X 1.5mm SOP8 package. Features and Benefits  Tunneling Magneto resistance (TMR) Technology  High Sensitivity (7~15mV/V/Oe)  Large Dynamic Range  Very Low Power Consumption  Excellent Thermal Stability  Very Low Hysteresis  Compatible with wide Range of Supply Voltages  Ultra Low Noise Spectral Density(＜1nT/sqrt(Hz)@1Hz) Applications  Weak Magnetic Field Sensing  Current Sensors TMR2922  Position and Displacement Sensing 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 1V. 1/4 Datasheet V1.0a Pin Configuration (Arrow indicates direction of applied field that generates a positive output voltage.)
