.
Note7: This is used to adjust the rotation direction changeover gain.
This capacitance valve and the gain are in inverse.
This capacitance is to prevent from output through current.
Note8: Be sure to set this bias so that the hall element output amplitude and common mode input voltage fall within
the ranges specified in the table of electrical characteristic.
Note9: The voltage must be set to fall within the common mode input voltage range of the control amp.
