before the reactive load prevents ringing and oscilla-
tion. At higher capacitive loads, AC performance will be
controlled by the interaction of the load capacitance
and isolation resistor. Figures 3a–3c show the effect of
an isolation resistor on the MAX4108/MAX4109/
MAX4308/MAX4309 closed-loop response.
Coaxial cable and other transmission lines are easily
driven when terminated at both ends with their charac-
teristic impedance. When driving back-terminated
transmission lines, the capacitance of the transmission
line is essentially eliminated.
ADC Input Buffers
Input buffer amplifiers can be a source of significant
errors in high-speed ADC applications. The input buffer
is usually required to rapidly charge and discharge the
ADC’s input, which is often capacitive (see the section
Driving Capacitive Loads). In addition, a high-speed
ADC’s input impedance often changes very rapidly
during the conversion cycle, requiring an amplifier with
very low output impedance at high frequencies to main-
tain measurement accuracy. The combination of high
speed, fast slew rate, low noise, and a low and stable
distortion over load makes the MAX4108/MAX4109/
MAX4308/MAX4309 ideally suited for use as buffer
amplifiers in high-speed ADC applications.
