DAC output buffer - DC offset

Hallo,

I have not found, in the stm32f100x reference manual or data sheet, any mentioning of a DC offset on the DAC.

But if use DAC_OutputBuffer_Enable, I get ~ 60 mV on the pins (nothing connected but a scope) when constantly writing zeroes to the DAC.

Is that normal behavior for an stm32, or is it some qirk on the discovery board?
Or perhaps, my stm32 is on the far end of tolerance or something ...

Regards
