AD5422, capacitive load

We see following description in AD5422 datasheet Rev.I page.27.


Driving Large Capacitive Loads

The voltage output amplifier is capable of driving capacitive loads of up to 1 μF with the addition of a nonpolarized 4 nF compensation capacitor between the CCOMP and VOUT pins. Without the compensation capacitor, up to 20 nF capacitive loads can be driven.


When compensation capacitor is below 4nF, to be more precise 330pF ~ 2200pF, what value of capacitive load can be driven ?

If you provide any documents, tables, or calculation formula would be very much appreciated.
