description
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, 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, 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 may be added to reduce the
settling time for 0.1% error band to under 1
µs.
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.
The LM118 is characterized for operation from
– 55°C to 125°C. The LM218 is characterized for
operation from – 25°C to 85°C, and the LM318 is
characterized for operation from 0°C to 70°C.
