Abstract:
A position sensor device comprises at least two Hall elements (11, 12) and a signal evaluation circuit (14) that is coupled on its input side to the at least two Hall elements (11, 12) and is designed to provide a digital position signal (ANS). Moreover, the position sensor device (10) comprises a processing unit (15) comprising a loop filter (16) that is coupled on its input side to the signal evaluation unit (14). The processing unit (15) is designed to adaptively control a filter parameter of the loop filter (16) during operation.
