I have an existing product that uses the DAC1220. I would like details regarding the C1 & C2 cap pins beyound what is in the data sheet. What does the circuit look like that is connected to those two pins? What is the impedance? How does the quality and microfads of the two caps effect the settling time of the final output? I am looking at a step to full scale and see it takes what seems like 30 seconds to settle to a final value in microvolts. During the 30 seconds, the level moved by tens of microvolts until the final value is reached. The reference input appears stable so it seems like these two caps may have something to do with that. Can soakage do this?
