For example, the output voltage swing of an op amp with a supply voltage of 15 V is ± 13V. Second, the output voltage of the IC op amps are usually one or two volts less than the voltage of the power supply.First, the maximum voltage of the power supply must not exceed the maximum rating, because it will damage the IC.In fact, IC Op-Amp are important limitations to consider. Op-Amp IC features very similar to the concept of the ideal Op-Amp circuit analysis.

LM741 IC contains an Op-Amp fruit, there are many other IC types that have two or more Op-Amp in a DIP package. Null offset pin allows us to do a little adjustment to the internal flow inside the IC to force the output voltage becomes zero when the input is zero. In this IC, there are two input pins, two pin power supply, an output pin, the pin NC (No Connection), and two null offset pin. IC LM741 has an 8-pin DIP packaging as shown in the following figure. Numbering ICs in DIP packaging is counter clockwise starting from the pin which lies closest to the round pins or strips on the DIP packaging. DIP IC packaging types have dots mark or strip on one of its corners to mark the direction of the pin or pin 1 of the IC. LM741 operational amplifier IC is packaged in a dual in-line package (DIP).

One of the types of operational amplifiers (Op-Amp) is a popular LM741. Operational Amplifiers (Op-Amp) packaged in an integrated circuit (IC-integrated circuit). Operational Amplifiers (Op-Amp) is a block amplifier that has two inputs and one output.
