National Semiconductor LM741 Amplifier
General Description
The LM741 series are general-purpose operational amplifiers that 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 make their 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/LM741E are identical to the LM741/LM741A except that the LM741C/LM741E have their performance guaranteed over a 0
C to a70C temperature range, instead of b55C to a125C.

Note 1: For operation at elevated temperatures, these devices must be derated based on thermal resistance, and Tj max. (listed under ‘‘Absolute Maximum Ratings’’). Tj =TA + (ojA PD).

Note 2: For supply voltages less than g15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3: Unless otherwise specified, these specifications apply for VS e g15V, b55C s TA s a125C (LM741/LM741A). For the LM741C/LM741E, these specifications are limited to 0C s TA s a70C.
