Hello,
I've tried to measure the offset of the DAC of the STM8L152C6 board. When the output buffer is disabled, I measured the dac output voltage on PF0 - 200 mV, which is what I should get according to the documentation. When I enabled the output buffer (cleared BOFF bit), I measured the offset to be 70 mV. I though it couldn't be that high, so I made the same measurements by using STM's wave generator, but results were the same. Shouldn't it be less than 70mV? Is there a way to decrease it?
