LM118/LM218/LM318
Operational Amplifiers
General Description
The LM118 series are precision high speed operational amplifiers
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 compensation.
This considerably simplifies its application since no
external components are necessary for operation. However,
unlike most internally compensated amplifiers, external frequency
compensation may be added for optimum performance.
For inverting applications, feedforward compensation
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
reduce the 0.1% settling time to under 1 μs.
