Hello,
I plan to use the ADA4084 as a DAC buffer in a low noise application. The DAC is used to generate a DC biasing voltage, and the ADA4084 is used as a unity gain voltage follower.
I plan to filter the DAC noise by a using a very low frequency RC low pass filter between the DAC output and the op amp non inverting input. I will typically use 100kR with 100 nF.
My question is : can a capacitor at the non inverting input of the ADA4084 can cause unstability ?
I know that a capacitance at the inverting input can cause unstabilty issue, but my intuition is that it not a concern for the non inverting output, as the capacitance is not in the feedback loop in that case.
Thank you,
Best regards,
Maxime Puech
