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.
