LM118/LM218/LM318
Operational Amplifiers
General Description
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 serieshas 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 canbe 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 is identical to the LM118 except that the LM218
has its performance specified over a −25˚C to +85˚C temperature range. The LM318 is specified from 0˚C to +70˚C.

Note 3: The maximum junction temperature of the LM118is 150˚C, the LM218 is 110˚C, and the LM318 is 110˚C. For operating at elevated temperatures, devices
in the H08 package must be derated based on a thermal resistance of 160˚C/W, junction to ambient, or 20˚C/W, junction to case. The thermal resistance of the
dual-in-line package is 100˚C/W, junction to ambient.
Note 4: The inputs are shunted with back-to-back diodes for overvoltage protection. Therefore, excessive current will flow if a differential input voltage in excess of
1V is applied between the inputs unless some limiting resistance is used.
Note 5: For supply voltages less than
±
15V, the absolute maximum input voltage is equal to the supply voltage.
Note 6: These specifications apply for
±
5V ≤ VS≤±20V and −55˚C ≤ TA≤ +125˚C (LM118), −25˚C ≤ TA≤ +85˚C (LM218), and 0˚C ≤ TA≤ +70˚C (LM318). Also,
power supplies must be bypassed with 0.1 µF disc capacitors.

15V.The LM118 is in a unity-gain non-inverting configuration. VINis stepped from −7.5V to +7.5V and vice versa. The slew
rates between −5.0V and +5.0V and vice versa are tested and guaranteed to exceed 50V/µs.
