OP177

ISOLATING LARGE CAPACITIVE LOADS

The circuit in Figure 27 reduces maximum slew-rate but allows

driving capacitive loads of any size without instability. Because

the 100 Ω resistor is inside the feedback loop, its effect on

output impedance is reduced to insignificance by the high open-

loop gain of the OP177.
