Angle Sensor TMR3002
The dual-axis output voltages of the TMR3002 TMR angle sensor are proportional to the sine and cosine of the angle of a magnetic field applied parallel to the surface of the sensor, which can be provided by a small magnet positioned above the device. The TMR3002 includes two Wheatstone bridges, which can be configured to output sine and cosine functions respectively. Each bridge includes four TMR sensor elements in a push-pull arrangement to produce a best-in-class peak-to-peak signal as large as 100% of the supply voltage, eliminating the need for amplification in many applications. Additionally, the unique TMR Wheatstone bridge technology accurately compensates the output against changes in ambient temperature. This sensor is assembled in a compact LGA8 package of 3.0 mm × 3.0 mm × 0.9 mm. Features and Benefits: Tunneling Magnetoresistance (TMR) Technology Large Output Signal without Amplification Dual-Axis 360° Angle Measurement Compatible with Wide Range of Supply Voltages High Resistance for Low Power Consumption Wide Air-Gap Tolerance Excellent Thermal Stability Compact LGA Package Applications: Rotary Position Sensors Rotary Encoders Contactless Potentiometers Valve Position Sensors Knob Position Sensors
