DAC output range when buffer ON

I have read the datasheet of stm32f407 about the DAC output range. When buffer on, the min DAC_OUT is 0.2V and max DAC_OUT is VDDA-0.2V.

However, I get 0.069V at 0x000 and 3.272V at 0xfff rather than 0.2V and 3.1V(My reference voltage is 3.3V) when I enable the DAC buffer.

Why would be that result? Does anyone have any ideal?
