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, R
S
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 R
SNUB
, is used
only when driving large capacitive loads. Using R
SNUB
improves
stability and minimizes ringing at the output. For more infor-
mation, see the Driving Capacitive Loads section.
