LM118/LM218/LM318 Operational Amplifiers General Description
The LM118ries are precision high speed operational am-plifiers designed for applications requiring wide bandwidth and high slew rate.They feature a factor of ten increa in speed over general purpo devices without sacrificing DC performance.
The LM118ries has internal unity gain frequency compen-sation.This considerably simplifies its application since no external components are necessary for operation.However, unlike most internally compensated amplifiers,external fre-quency compensation may be added for optimum perfor-mance.For inverting applications,feedforward compensa-tion will boost the slew rate to over150V/µs and almost double the bandwidth.Overcompensation can be ud with the amplifier for greater stability
when maximum bandwidth is not needed.Further,a single capacitor can be added to reduce the0.1%ttling time to under1µs.
The high speed and fast ttling time of the op amps make them uful in A/D converters,oscillators,active filters,sample and hold circuits,or general purpo amplifiers. The devices are easy to apply and offer an order of magnitude better AC performance than industry standards such as the LM709.
The LM218is identical to the LM118except that the LM218 has its performance specified over a−25˚C to+85˚C tem-perature range.The LM318is specified from0˚C to+70˚C. Features

Note 2:The maximum junction temperature of the LM118is 150˚C,the LM218is 110˚C,and the LM318is 110˚C.For operating at elevated temperatures,devices in the H08package must be derated bad on a thermal resistance of 160˚C/W,junction to ambient,or 20˚C/W,junction to ca.The thermal resistance of the dual-in-line package is 100˚C/W,junction to ambient.
Note 3:The inputs are shunted with back-to-back diodes for overvoltage protection.Therefore,excessi
ve current will flow if a differential input voltage in excess of 1V is applied between the inputs unless some limiting resistance is ud.
Note 4:For supply voltages less than ±15V,the absolute maximum input voltage is equal to the supply voltage.
Note 5:The specifications apply for ±5V ≤V S ≤±20V and −55˚C ≤T A ≤+125˚C (LM118),−25˚C ≤T A ≤+85˚C (LM218),and 0˚C ≤T A ≤+70˚C (LM318).Also,power supplies must be bypasd with 0.1µF disc capacitors.
Note 6:Slew rate is tested with V S =±15V.The LM118is in a unity-gain non-inverting configuration.V IN is 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.Note 7:Refer to RETS118X for LM118H and LM118J military specifications.Note 8:Human body model,1.5k Ωin ries with 100pF.
