External Parts
Note6: Absorb switching noise by C
Note7: This is used to adjust the rotation direction changeover gain.
Note8: Be sure to set this bias so that the hall element output amplitude and common mode input voltage fall within
Note9: The voltage must be set to fall within the common mode input voltage range of the control amp.
