LM118/LM218/LM318

Operational Amplifiers

General Description

The LM118 series are precision high speed operational am-

plifiers 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.

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 tem-

perature range. The LM318 is specified from 0˚C to +70˚C.

The LM118 series 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 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.

Features

n 15 MHz small signal bandwidth

n Guaranteed 50V/µs slew rate

n Maximum bias current of 250 nA

n Operates from supplies of 5V to 20V

n Internal frequency compensation

n Input and output overload protected

n Pin compatible with general purpose op amps

The high speed and fast settling time of these op amps make

them useful in A/D converters, oscillators, active filters,

Note 2: The maximum junction temperature of the LM118 is 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 3: 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 4: For supply voltages less than 15V, the absolute maximum input voltage is equal to the supply voltage.

Note 5: These specifications apply for 5V ≤ V

≤

20V and −55˚C ≤ T ≤ +125˚C (LM118), −25˚C ≤ T ≤ +85˚C (LM218), and 0˚C ≤ T ≤ +70˚C (LM318). Also,

A A A

power supplies must be bypassed with 0.1 µF disc capacitors.

Note 6: Slew rate is tested with V 15V. The LM118 is in a unity-gain non-inverting configuration. V 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, 1.5 kΩ in series with 100 pF.
