description/ordering information
The LM118, LM218, and LM318 are precision,
fast 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.

These operational amplifiers have internal
unity-gain frequency compensation. This
considerably simplifies their application because
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,
feed-forward compensation boosts the slew rate
to over 150 V/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 settling time
for 0.1% error band to under 1 µs.
NC – No internal connection
The high speed and fast settling time of these operational amplifiers make them useful in A/D converters,
oscillators, active filters, sample-and-hold circuits, and general-purpose amplifiers.
