Data Sheet IC Operational amplifier
- 1. 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.
