In the document, the input level is limited by Vref+ and Vref-. But Vref- seems to be tied to GND in general, which implies a negative value cannot be converted without problem.Can Vref- be connected external -5V or -3.3 V for handling a negative val...

MCU of STM32L476 series,please let me know the maximum sample time of DAC and the maximum sine signal frequency which can be generated.

Do you mean that I have to use an OP-AMP Circuit as shown below?Please let me know.

Thank you very much.In the page you mentioned, there is some formula (???), but no value in MSPS,You may mean I have to calculate the maximum DAC sample rate based on the Clock frequency and Timer setting.Am I right ???If yes, I may calculate the val...

For ADC input, my input signal is sinusoidal with no DC, that is, it has positive and negative value. Is it possible to convert a negative value without problem?
