Part Number: OPA828
Hi,
I am considering using OPA828 to buffer a voltage reference for a 15 MSPS SAR ADC, which asks for a 10uF MLCC cap on the reference input pin. I have seen some circuits where the op-amp directly drives the large cap and is stable due to the large value. There are other circuits which use techniques like a series resistor inside the loop with compensation, or an RC snubber. Can the OPA828 be used with a large cap 1-10uF at the output, and if not, which circuit would provide the best performance? Other parts or a composite amplifier would be acceptable too, but OPA828 has a good combination of DC specs and voltage noise.
Thanks,
Chris
