DAC5578: Capacitive load and stability

Part Number: DAC5578

The data sheet for DAC5578SPW state "Capacitive load stability" is typ 1nF.

What would the implication if the outputs where loaded with 1uF in parallel with 680Ohm?

Is there a recommendation for serial output resistance if capacitive load should be driver?

Hi Yngve,

Your isolation resistor is large enough that I do not think you will have any stability issues. We do not have a model for this DAC, but a value >500Ω should be good in my estimation.

Thanks,

Paul
