Snubber Network
Another way to stabilize an op amp driving a capacitive
load is with the use of a snubber, as shown in Figure 9.
This method presents the signi?cant advantage of not
reducing the output swing because there is not any
isolation resistor in the signal path. Also, the use of
the snubber does not degrade the gain accuracy or
cause extra distortion when driving a nonlinear load.
The exact R S and C S combinations can be determined
experimentally.
