LM118/LM218/LM318
Operational Amplifiers
General Description
The LM118 series are precision high speed operational am-
plifiers designed for applications requiring wide bandwidth
and high slew rate. They feature a factor of ten increase in
speed over general purpose devices without sacrificing DC
performance.
The LM118 series has internal unity gain frequency compen-
sation. This considerably simplifies its application since no
external components are necessary for operation. However,
unlike most internally compensated amplifiers, external fre-
quency compensation may be added for optimum perfor-
mance. For inverting applications, feedforward compensa-
tion will boost the slew rate to over 150V/µs and almost
double the bandwidth. Overcompensation can be used with
the amplifier for greater stability when maximum bandwidth
is not needed. Further, a single capacitor can be added to re-
duce the 0.1% settling time to under 1 µs.
The high speed and fast settling time of these op amps make
them useful in A/D converters, oscillators, active filters,
sample and hold circuits, or general purpose amplifiers.
These devices are easy to apply and offer an order of mag-
nitude better AC performance than industry standards such
as the LM709.
The LM218 is identical to the LM118 except that the LM218
has its performance specified over a −25˚C to +85˚C tem-
perature range. The LM318 is specified from 0˚C to +70˚C.
