VTC VA052 Magnetic Sensor
VA052 is a miniature MR sensor offering user friendly and cost competitive solution. VA052 also shows significant advantages of high sensitivity in low magnetic field, low cross-axis and low linearity errors as well as low power consumption while applying to measure the direction or the magnitude of Earth¡¯s magnetic fields such as E-Compasses, Navigations. VA052 is a superior two-axis magnetic sensor which utilizes VTC¡¯s unique technology and anisotropic magneto-resistive (AMR) technique. The concept of transduction can easily be understood from Wheatstone bridge design. In addition to bridge section, two physically coils include Set/Reset and Offset are integrated for calibration of magnetic direction and build-in self test.
