1) On pins with overlaid GPIO function the max. limit increases by up to 25 mV due to leakage current for TJ > 150°C.
2) For detailed information, refer to the User Manual chapter.
3) This parameter is valid within the defined range of fMOD
.
4) Gain mismatch error between the different EDSADC channels is within ±0.5% if they have the same calibration strategy
