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 applica-
tion 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/LM741E are identical to the LM741/LM741A
except that the LM741C/LM741E have their performance
guaranteed over a 0�C to +70�C temperature range, instead
of -55�C to +125�C.
