Introduction to uA 741 Op-Amp

About the uA741 Op-amp IC

The 741 IC was designed by Dave Fullagar of Fairchild Semiconductor in 1968. The 741 IC is the successful predecessor of the LM 101 IC, and the only difference between the two was that an additional 30pF internal compensation capacitor was added for the 741 IC. But, this simple addition has made this IC evergreen in the electronics world and is still manufactured by different companies in different versions and specifications, and is made recognizable by adding the famous number 741 in the series.

The 741 IC is developed using the planar epitaxial process (Refer:- Epitaxial Devices – Characteristics). The IC is made ideal for use as integrator, summing amplifier, voltage follower and other basic applications.

The 741 IC is available in the market as 8-pin metal can, 10-pin flat pack, 8 or 14 pin DIP. The pin configuration for thse packages are shown below.
