FEATURES

DESCRIPTION

The

LM118

series

are

precision

high

speed

2

•

15 MHz Small Signal Bandwidth

operational

amplifiers

designed

for

applications

•

Ensured 50V/

μs Slew Rate

requiring wide bandwidth and high slew rate. They

•

Maximum Bias Current of 250 nA

feature a factor of ten increase in speed over general

purpose devices without sacrificing DC performance.

•

Operates from Supplies of ±5V to ±20V

•

Internal Frequency Compensation

The LM118 series has internal unity gain frequency

compensation.

This

considerably

simplifies

its

Input and Output Overload Protected

application

since

no

external

components

are

•

Pin Compatible with General Purpose Op

necessary

for

operation.

However,

unlike

most

Amps

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 can be 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-N is identical to the LM118 except that

the LM218-N has its performance specified over a

−25°C to +85°C temperature range. The LM318-N is

specified from 0°C to +70°C.

Fast Voltage Follower

Do not hard-wire as voltage follower (R1

≥ 5 kΩ)
