AD5522 Ccomp function

Hi, Mannyma. 

AD5522 includes an opamp to drive current to a load. More often than not, the load include capacitances, wanted or unwanted. Instability becomes a problem when driving capacitive loads using opamps, thus the need for compensation capacitors.

When using these compensation capacitors, the gain-bandwidth product of the opamp gets compromised, effectively leading to slower settling time.

You may check out this stability video series from Matt Duff on Youtube for a more in-depth discussion on the matter:
