One of my customer is considering ADR06.
The capacitive load would be 4uF. Can ADR06 drive it?
Should they use buffer amplifier?
If you have advice, it is helpful.
Yes, that should be fine. It is actually recommended on its datasheet to put an additional 1 uF to 10 uF electrolytic, tantalum or ceramic capacitor at the output to improve transient performance response to sudden changes in load current.
Let me know if you need anything else.
