Hi Evan, DAC8830 is an unbuffered DAC. The settling time is dominated by the output buffer you select. The settling time we give in the datasheet is really just the time the DAC takes to rise/fall to the expected output. For an unbuffered DAC this is just an RC time constant of the DAC ladder resistance (6.25kΩ) and any parasitic output capacitance. Best, Katlynne Jones
