Adaptive Noise Filter AS5047U, AS5147U, AS5247U
■In all products of the magnetic position sensor product family AS5x47U, an adaptive noise filter is implemented to reduce random measurement errors.
■Based on the implemented filter, it is possible to reduce the random measurement error, respectively the output noise, by a factor of six. Due to the adaptive approach, the capability to deal with very dynamic systems is not affected. Rotation speed up to 28000 rpm in combination with massive acceleration rates are handled without any constraints. It is guaranteed, that no positions or measurement points will get lost due to filtering.
■The application note gives a deep insight into the filter design and implementation. Many details about timing and function are explained. To optimize system performance it is possible to adapt filter parameters, although the default settings will fit to most of all possible applications
