TMR2104P

Datasheet V1.0a TMR2104 Large Dynamic Range TMR linear sensor General Description The TMR2104 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 TMR2104 is available in 6 mm X 5 mm X 1.5 mm SOP8 and 3mm×3mm×0.75mm DFN8L package. Features and Benefits  Tunneling Magneto resistance (TMR) Technology  High Sensitivity  Large Dynamic Range  Low Power Consumption  Excellent Thermal Stability Applications  Magnetic Field Sensing  Current Sensors  Displacement Sensing  Rotary Position Sensors TMR2104 Transfer Curve The following figure shows the response of the TMR2104 to an applied magnetic field in the range of ±80 Oe (left) and ±200 Oe (right) when the TMR2104 is biased at 1 V. 1/5 Datasheet V1.0a Pin Configuration (Arrow indicates direction of applied field that generates a positive output voltage.)
