ADS1284: stability

user1919277
Prodigy 10 points
Part Number: ADS1284

We are currently evaluating the ADS1284.
We felt that the output stability of the ADC was higher than expected, so we enabled the Internal Short feature.
However, the output stability of the ADC did not improve. Please give me some advice.

Our evaluation environment is as follows. The evaluation board is the board we designed.
AVDD: + 5V, DVDD: 3V, VREF: 1V, fclk: 2MHz, Config0: 00010010, Config1: 00101000

    Hi,

    I'm not sure I fully understood the issue. Are you seeing higher than expected noise on the output? If so, please let me know what kind of signal you are measuring and what noise levels you are observing? Also, if you have a schematic you could share it would be helpful.
