CIRCUIT CONFIGURATIONS
WIDEBAND OPERATION
Figure 61 and Figure 62 show the recommended circuit
configurations for noninverting and inverting amplifiers. In
unity-gain (G = +1) applications, RS helps to reduce high
frequency peaking. It is not needed for any other configurations.
For more information on layout, see the Printed Circuit Board
Layout section.
The resistor at the output of the amplifier, labeled RSNUB, is
used only when driving large capacitive loads. Using RSNUB
improves stability and minimizes ringing at the output. For
more information, see the Driving Capacitive Loads section.
