The MLX90380 is a monolithic contactless sensor IC
sensitive to the flux density applied orthogonally and
parallel to the IC surface.
High-speed dual analog outputs allow the MLX90380 to
deliver accurate sine/cosine signals when used with a
rotating permanent magnet.
With a wide range of operating temperature, supply
voltage and magnetic flux density, the MLX90380 can
resolve the angular position of a rotating axis over 360
degrees in many industrial and automotive
applications.
Selectable magnetic axes ensure compatibility with
end-of-shaft and through-shaft configurations.
Sensitivity and filter bandwidth can be programmed
through the 4 application pins to optimally use the ADC
input range of the companion MCU.
