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.
