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.
