TMS320F28335 ADC values are not stable

Other Parts Discussed in Thread: TMS320F28335

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
