To improve step response when R′ > 2kΩ, connect small
capacitor Cf between the inverting input and output.
Choose Cf as follows:
Cf = 8(R/Rf) [pf]
where Rf is the feedback resistor and R is the gain-setting
resistor (Figure 5).
Driving Capacitive Loads
The MAX4230–MAX4234 have a high tolerance for
capacitive loads. They are stable with capacitive loads up
to 780pF. Figure 6 is a graph of the stable operating region
for various capacitive loads vs. resistive loads.Figures 7
and 8 show the transient response with excessive capaci-
tive loads (1500pF), with and without the addition of an
isolation resistor in series with the output. Figure 9 shows
a typical noninverting capacitive-load-driving circuit in the
unity-gain configuration.
