LM741 Operational Amplifier

Literature Number: SNOSC25B

LM741

Operational Amplifier

General Description

The LM741 series are general purpose operational amplifi-

ers which feature improved performance over industry stan-

dards like the LM709. They are direct, plug-in replacements

for the 709C, LM201, MC1439 and 748 in most applications.

The amplifiers offer many features which make their appli-

cation nearly foolproof: overload protection on the input and

output, no latch-up when the common mode range is ex-

ceeded, as well as freedom from oscillations.

The LM741C is identical to the LM741/LM741A except that

the LM741C has their performance guaranteed over a 0˚C to

+70˚C temperature range, instead of −55˚C to +125˚C.
