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.
