Q
Are there any limitations for the AD8629 when driving capacitive load of 10 nFwith 5V supply? If not, what are the limits?
A
There is some information in the datasheet about the tolerance of loadcapacitance.
Figures 23-26 give the typical overshoot for 300pF and 50pF with no resistive
load.
Figures 27 and 28 show the percentage overshoot vs capacitive load for a 2k
Ohms resistive load. You can see that the instability becomes very significant
for load capacitance greater than 100pF.
Therefore I would expect that there will be serious instability problems if the
AD8629 is directly driving a 10nF capacitive load.
