    Hello Xinyun,

    The part will not change gain as it is already closed loop system.  To change the Gain pick the correct gain option and change the shunt resistance.  RL is not available.  This is the only way to keep the internal resistors matched to get the good gain error from these devices.  If there were a way to change the gain the datasheet would mention it.

    Regards,
