DESCRIPTION
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.
