Part Number:TM4C123GH6PM
I have questions on using the ADC on the TM4C.
I have an external circuit supplying the voltage to the ADC.
I have multiple boards running the same firmware, but the ADC values do not agree with the same voltage input.
I have noticed that there is a slight variation in VDDA from board to board.
How accurate is VDDA expected to be?
If VDDA is accurate to V3.300, how much variation is expected in the ADC input? Meaning what is expected variation of the ADC itself.
How much changed in ADC input is seen with a 0.1% change in VDDA?
