Infineon Technologies TLE5309D Dual GMR/AMR Angle Sensors

Infineon Technologies TLE5309D Dual GMR/AMR Angle Sensors are diverse redundant angle sensors with analog outputs. The TLE5309D series combines a Giant Magneto Resistance (GMR) sensor for full 360° angle range. The devices also have an Anistropic Magneto Resistance (AMR) sensor for high precision in a flipped configuration in one package. Sine and cosine angle components of a rotating magnetic field are measured by Magneto Resistive (MR) elements. The sensors provide analog sine and cosine output voltages that describe the magnetic angle in a range of 0 to 180° (AMR sensor), and 0 to 360° (GMR sensor), respectively. The differential MR bridge signals are independent of the magnetic field strength, and the analog output is designed for differential or single-ended applications. The output voltages are designed to use the dynamic range of an A/D-converter using the same supply as the sensor as a voltage reference. Both sensor ICs are supplied independently by separate supply and ground pins.
