The LM118 is a precision high speed operational amplifier designed for applications
requiring wide bandwidth and high slew rate. It features a factor of ten increase in speed over
general purpose devices without sacrificing DC performance.
The LM118 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, feed forward 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 this op amp makes it useful in A/D converters,
oscillators, active filters, sample and hold circuits, or general purpose amplifiers. This device
is easy to apply and offers an order of magnitude better AC performance than industry standards
such as the LM709.
