LM741 Operational Amplifier

1 Features 3 Description

The LM741 series are general-purpose operational

• Overload Protection on the Input and Output

amplifiers which feature improved performance over

• No Latch-Up When the Common-Mode Range is

industry standards like the LM709. They are direct,

Exceeded

plug-in replacements for the 709C, LM201, MC1439,

and 748 in most applications.

2 Applications

The amplifiers offer many features which make their

• Comparators

application nearly foolproof: overload protection on

the input and output, no latch-up when the common-

• Multivibrators

mode range is exceeded, as well as freedom from

• DC Amplifiers

oscillations.

• Summing Amplifiers

The LM741C is identical to the LM741 and LM741A

• Integrator or Differentiators

except that the LM741C has their performance

• Active Filters

ensured over a 0°C to +70°C temperature range,

instead of −55°C to +125°C.
