Hello,
We are configured ADC in TMS320F28335 as follows:
ADC = 25MHz, Aqu. window = 2, Sequential sampling, Internal band gap reference
In order to check the ADC accuracy we have connected stable precision DC source (connected through opamp buffer) to one of the ADC inputs. But ADC values are not stable and oscillating 20bits.
What could be the issue in ADC values variations?
regards
