This is usually done by raising the standing dc input voltage to the non-inverting input terminal to approximately half the supply voltage by a voltage divider network. It is possible to operate the 741 on a single rail supply also. We will be discussing all these parameters at normal temperature mode and at supply voltages of +VCC = +15V and -VEE = -15V. The other mode is applicable for a commercial temperature range from 0☌ to +70☌. One mode is applicable for the normal operation of the IC at room temperature of 25☌. The electrical parameter specifications for the 741 IC is provided in 2 modes. The equivalent circuit is same for all models of the 741 IC. This equivalent circuit illustrates the internal structure of the 741 op-amp and also helps to clarify the capabilities and limitations of the op-amp. The equivalent circuit or schematic diagram of the 741 IC is provided in the datasheet. The datasheet of the LM 741 IC is provided here. The manufacturers advise not to exceed these maximum ratings even under the worst operating conditions. The maximum ratings of the IC are specified for parameters like supply voltage, input and differential input voltages, storage and operating temeprature ranges, soldering pin temperatures, and output short circuit duration. The pin configuration for thse packages are shown below. The 741 IC is available in the market as 8-pin metal can, 10-pin flat pack, 8 or 14 pin DIP.

The IC is made ideal for use as integrator, summing amplifier, voltage follower and other basic applications. The 741 IC is developed using the planar epitaxial process (Refer:- Epitaxial Devices – Characteristics). 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 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. The 741 IC was designed by Dave Fullagar of Fairchild Semiconductor in 1968. In this post, we will be discussing about the 741 IC, one of the most popularly used op-amp IC. We have already discussed in detail about the basics on operational amplifier, its block diagram, symbol, different characteristics, and its circuit diagram (Refer:- Op Amps-Operational Amplifiers).
