可直接换HMC1052
Product Features � Mainstream Two-Axis Magneto-resistive Sensor � Magnetic Field Range (+/- 6 Gauss) � High Sensitivity, Low Cross-Axis and Low Linearity Errors � Miniature Surface Mount QFN Package (3mm x 3mm) � Integrated Set/Reset, Offset and BIST Coils Applications � E-Compassing � Navigation � Magnetometry � Traffic Detection � Current Measurement 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.
