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.

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.
