Driving Capacitive Loads
In conjunction with op amp output resistance, capaci-
tive loads introduce a pole frequency that can reduce
phase margin and lead to unstable operation. The
MAX4490/MAX4491/MAX4492 drive capacitive loads
up to 300pF without significant degradation of step
response and slew rate (Figure 4). Capacitive-Load
Stability (page 1) shows regions of stable and margin-
ally stable (step overshoot <10%) operation for different
combinations of capacitive and resistive loads.
Improve stability for large capacitive loads by adding
an isolation resistor (typically 10
) in series with the
output (Figure 5). Note that the isolation resistor forms a
voltage divider with potential for gain error.
