LM741 Operational Amplifier

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

Note 3: For supply voltages less than ± 15V, the absolute maximum input voltage is equal to the supply voltage. Note 4: Unless otherwise specified, these specifications apply for VS = ± 15V, −55˚C ≤ TA ≤ +125˚C (LM741/LM741A). For the LM741C/LM741E, these specifications are limited to 0˚C ≤ TA ≤ +70˚C. Note 5: Calculated value from: BW (MHz) = 0.35/Rise Time(µs). Note 6: For military specifications see RETS741X for LM741 and RETS741AX for LM741A.
