Figure 8. Capacitive Load vs. Isolation Resistance
Figure 7. Figure 8 is a graph of the optimal isolation resis-
tor versus load capacitance. Figure 9 shows the frequen-
cy response of the MAX4014/MAX4017/MAX4019/
MAX4022 when driving capacitive loads with a 27 isola-
tion resistor.

Coaxial cables and other transmission lines are easily dri-
ven when properly terminated at both ends with their
characteristic impedance. Driving back-terminated trans-
mission lines essentially eliminates the lines’ capacitance.
