MAX4212/MAX4213/MAX4216/MAX4218/MAX4220
Output Capacitive Loading and Stability
The MAX4212/MAX4213/MAX4216/MAX4218/MAX4220
are optimized for AC performance. They are not
designed to drive highly reactive loads, which de-
creases phase margin and may produce excessive
ringing and oscillation. Figure 5 shows a circuit that
eliminates this problem. Figure 6 is a graph of the opti-
mal isolation resistor (RS) vs. capacitive load. Figure 7
shows how a capacitive load causes excessive peak-
ing of the amplifier’s frequency response if the capaci-
tor is not isolated from the amplifier by a resistor. A
small isolation resistor (usually 20
to 30) placed
before the reactive load prevents ringing and oscilla-
tion. At higher capacitive loads, AC performance is
controlled by the interaction of the load capacitance
and the isolation resistor. Figure 8 shows the effect of a
27
isolation resistor on closed-loop response.
Coaxial cable and other transmission lines are easily
driven when properly terminated at both ends with their
characteristic impedance. Driving back-terminated
transmission lines essentially eliminates the line’s
capacitance.
