LM741
Operational Amplifier
General Description
The LM741 series are general purpose operational amplifiers
which feature improved performance over industry standards
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 maketheir application
nearly foolproof: overload protection on the input and
output, no latch-up when the common mode range is exceeded,
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.
