I do have a SAM E70 Xplained development board.
When I was looking at the ADC function, I saw that the ADC clock frequency can be varied between pclk/2 to pclk/512.
I really want to know why we need to change the frequency of ADC conversion?
Why don't we fix it at the highest frequency available?
In my case, my pclk is 150MHz.
My requirement is to sample AC voltage.
Can anybody help me with this?
