It is better. > I read something about internal calibration? There is a built-in voltage divider network, providing two data points (Vref*0.25 and Vref*0.75), which can be used for calibration. The utility of this feature to you depends on your application. > How good is the internal reference-voltage of the ADC? It is improved over the 80x series. > Is the ADC a complete re-design or is it the old one of the 56F803? The ADC module in the 56F8300 series is a redesign of the 80x series incorporating lessons learned. It offers more consistent performance over temperature and ADC clock speed. The ADC module offers additional features, such as smart power-down/Power-up to/from low power modes. > Thank you very much! > > Thomas |
