AD8009 capacitive load drive capability

There Folks

I designed an input, output AC Coupled amplifier by AD8009. output ac couple circuit has a 47u capacitor.

are there any issues for ad8009 to working with this cap value as an output ac coupling?

Hi,

Can you show your schematic, 47uF seems too large. What will be the next stage after the AD8009? What is your load?

Regards,
Goz

if im going to put a series resistor with ad8009 output, does it solve the problem due to large capacitive load or not? if it does, how can i calculate the proper value of series resistor based on value of ac decoupling capacitor?
