tha op-amp is works the principle of the electronics. it is consist of several capasitors and transistors. As requirement of the user it can be use as a inverting ,non-inverting amlifires, frequency genarator, osilators,etc.
The 741 is a general purpose operational amplifier which features improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and...
Hi there, I've written a post explaining this idea in simple terms. Hope you enjoy it! http://chrisgammell.com/2008/08/02/how-does-an-op-amp-work-part-1/ ~Chris Gammell
op amp can perform mathematical operations such as summing,subtracting differentiating,scaling,integrating which an amplifier can't perform. hence op is called as op amp & not just an amplifier....
An operational amplifier, which is often called an op-amp, is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.[1] An op-amp produces...
