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
according to datasheet, large cap load may be cause non-stability or oscillation in high frequencies, so what is this range? in 1 MHz or 2 MHz this non-stability could be accrued in 1 or 2 MHz till 30 MHz or amplifier may be oscillate in frequencies above this numbers?
