We are sampling an ADC channel which has DC voltage at its input. ADC count which we are getting has variations of 10 -15 counts . This we observed in NXP SDK on Eval board too.
Core clock is 48 MHz, Peripheral functional clock is FIRC DIV2 /2 .
We are using a stable power supply, I hope there is no ripple/Spike... Can you suggest
