very low output impedance at high frequencies to main-
tain measurement accuracy. The combination of high
speed, fast slew rate, low noise, and low distortion
makes the MAX4223–MAX4228 ideally suited for use as
buffer amplifiers in high-speed ADC applications.
Video Line Driver
The MAX4223–MAX4228 are optimized to drive coaxial
transmission lines when the cable is terminated at both
ends, as shown in Figure 3. Note that cable frequency
response may cause variations in the signal’s flatness.
Driving Capacitive Loads
A correctly terminated transmission line is purely resis-
tive and presents no capacitive load to the amplifier.
Although the MAX4223–MAX4228 are optimized for AC
performance and are not designed to drive highly
capacitive loads, they are capable of driving up to
25pF without excessive ringing. Reactive loads
decrease phase margin and may produce excessive
ringing and oscillation (see
Typical Operating
Characteristics). Figure 4’s circuit reduces the effect of
large capacitive loads. The small (usually 5
to 20)
isolation resistor RISO, placed before the reactive load,
prevents ringing and oscillation at the expense of a
small gain error. At higher capacitive loads, AC perfor-
mance is limited by the interaction of load capacitance
with the isolation resistor.
Maxim’s High-Speed
Evaluation Board Layout
Figures 7 and 8 show a suggested layout for Maxim’s
high-speed, single-amplifier evaluation boards. These
boards were developed using the techniques described
above. The smallest available surface-mount resistors
were used for the feedback and back-termination resis-
tors to minimize the distance from the IC to these resis-
tors, thus reducing the capacitance associated with
longer lead lengths.
SMA connectors were used for best high-frequency
performance. Because distances are extremely short,
performance is unaffected by the fact that inputs and
outputs do not match a 50
line. However, in applica-
tions that require lead lengths greater than 1/4 of the
wavelength of the highest frequency of interest, con-
stant-impedance traces should be used.
Fully assembled evaluation boards are available for the
MAX4223 in an SO-8 package.
