TMR2001S

Datasheet V1.0a TMR2001 TMR Linear Sensor General Description The TMR2001 linear sensor utilizes a unique push-pull Wheatstone bridge composed of four TMR sensor elements. The TMR2001 is available in a 3 mm X 3 mm X 1.45 mm SOT23-5 package. Features and Benefits  Tunneling Magneto resistance (TMR) Technology  High Sensitivity  Low Power Consumption  Excellent Thermal Stability  Compatible with Wide Range of Supply Voltages  No need for set/reset calibration Applications  Weak Magnetic Field Sensing  Current Sensors TMR2001  Position and Displacement Sensing Transfer Curve The following figure shows the response of the TMR2001 to an applied magnetic field in the range of ±5 Oe and ±200 Oe when the TMR2001 is biased at 1V. 1/4 Datasheet V1.0a Pin Configuration (Arrow indicates direction of applied field that generates a positive output voltage.)
