UNITY GAIN PULSE RESPONSE CONSIDERATION
A pull-up resistor is well suited for increasing unity-gain, pulse response stability. For example, a 600
pull-up
resistor reduces the overshoot voltage by about 50%, when driving a 220 pF load. Figure 34 shows how to
implement the pull-up resistor for more pulse response stability.
Figure 34. Using a Pull-up Resistor at the Output for Stabilizing Capacitive Loads
Higher capacitances can be driven by decreasing the value of the pull-up resistor, but its value shouldn't be
reduced beyond the sinking capability of the part. An alternate approach is to use an isolation resistor as
illustrated in Figure 35 .
Figure 36 shows the resulting pulse response from a LMV824, while driving a 10,000 pF load through a 20
isolation resistor.
