The CMOS device iC-MA consists of a quadruple Hall sensor array which has been optimized for the magnetic measurement of angles of rotation.
With the aid of the integrated 8-bit sine/digital converter the angle of rotation is determined from the sine/cosine signals. This is output via an incremental interface in a number of selectable resolutions. The zero angle is indicated by an index pulse. The maximum resolution of 8-bit is maintained up to rotations of 60 000 rpm.
