LM318 General Purpose Amplifier

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.
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 magnitude better AC
performance than industry standards such as the LM709.
The LM218-N is identical to the LM118 except that the LM218-N has its performance
specified over a
−25°C to +85°C temperature range. The LM318-N is specified from 0°C to +70°C.
