Hi,

Are there any software examples available about improving the ADC accuracy by using Vref?

I’m trying to eliminate conversion errors due to Vref fluctuations.

Thanks

Hi,

I know AN2834.

I'm now measuring the VREF_INT channel, but I don't know if and how it can be used as a reference for analog conversion of regular channels. I think I need the value VREF+, I'm I correct?

Thanks
