Hi,
what is a reasonable safety factor for the previous stage’s current vs the required current to ensure the needed slew rate for the following stage? 2x, 5x, 10x?
Thank you in advance,
Roberto

Basically a safety factor is what you think it should be. Totally personal preference.
Why use my preference?

Safety factor to ensure that the required slew rate is still met with some exemplaric spread or to ensure negligible subslewing TIM at the specified signal rate of change?
In the first case, a factor of two should be enough. In the second case, it depends on all sorts of things.

VAS Current that is used up charging Cdom is not available to drive the base of the driver/output. How much “overhead” you need depends on the gain in the followers. If you’ve barely got enough VAS current to drive them, you can’t afford to have something else robbing it. If you have a ton of gain (ie a triple EF) you can afford to divert it to Cdom.
