Hi Jignesh,

Hope you got the answer.

The one thing that the experts have pointed out is interesting. Handling a mixed signal MCU ( with ADC / DAC in built ) needs much more engineering skills in terms of PCB and track layout as compared to external analog devices to achieve the required precision or make it equal to resolution..

SO when there is a need to use one of these MCUs with built in ADC, go thorugh the data sheet with a magnifier and adhere to every one of the recomendations on the grounding layout.
