Driving Capac itive Loads
When driving 50
or 75
back-terminated transmission
lines, capacitive loading is not an issue. The MAX4102/
MAX4103 can typically drive 5pF and 20pF, respectively.
Figure 3a illustrates how a capacitive load influences the
amplifier’s peaking without an isolation resistor (R
S
).
Figure 3b shows how an isolation resistor decreases the
amplifier’s peaking. By using a small isolation resistor
between the amplifier output and the load, large capaci-
tance values may be driven without oscillation (Figure
4a). In most cases, less than 50
is sufficient. Use Figure
4b to determine the value needed in your application.
Determine the worst-case maximum capacitive load you
may encounter and select the appropriate resistor from
the graph.
