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 is identical to the LM741/LM741A except that the LM741C has their performance guaranteed over a 0°C to +70°C temperature range, instead of -55°C to +125°C.
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.
Nobody invented the op-amp but manufactures decided that an amplifier can be more efficient as opposed to building the same amplifier out of discreet components

The op amp is an electronic device consisting of a complex arrangement of resistors, transistors, capacitors, and diodes. Here is a link to a 741 Op-Amp design... http://www.play-hookey.com/analog/inside_741.html

How ic 741 works?
A 741 Op-amp has three distinct parts and applications. They are a differential amplifier, a voltage amplifier, and an output amplifier.
High gain high input impedance low output impedance
An operational amplifier (op-amp) is a high-gain electronic voltage amplifier. The 741 IC type op-amp is a small scale integrated circuit. There is no actual reason for it be called 741, the number is an arbitrary designator assigned simply to make it possible to identify the part and look it up in a databook. The number was originally assigned as a member of the 7xx series of SSI bipolar analog integrated circuits in the middle 1960s, 741 was probably just the next unassigned number available.

In ua741 ua stands for nothing it is just the name of the ic ... Like every person have a name it similar to that one .UA is to show that the ic is manufactured by Fairchild. It is actually μa.

the op amp is a one IC which does not work at hige volteg so the IC not consumed the high frequncy
