Capacitive Loads
The LT6011/LT6012 can drive capacitive loads up to 500pF
in unity gain. The capacitive load driving capability increases
as the amplifier is used in higher gain configurations. A small
series resistance between the output and the load further
increases the amount of capacitance that the amplifier can
drive.

Rail-to-Rail Operation
The LT6011/LT6012 outputs can swing to within millivolts
of either supply rail, but the inputs can not. However, for
most op amp configurations, the inputs need to swing less
than the outputs. Figure 1 shows the basic op amp configu-
rations, lists what happens to the op amp inputs and speci-
fies whether or not the op amp must have rail-to-rail inputs.
Select a rail-to-rail input op amp only when really neces-
sary, because the input precision specifications are usually
inferior.
