Hello, I have been researching operational amplifiers because I plan on using some in a circuit I wish to build, but have been stuck for awhile on the concept of the maximum current that can be handled by the non-inverting input. It appears as though the input bias current is the current necessary to cause the transistors within the op amp to function, and it seems logical to assume that the Input bias current (max) [ as is stated on the filter selection for these amplifiers http://www.mouser.com/Semiconductors/Amplifier-ICs/Operational-Amplifiers-Op-Amps/_/N-4h00g?FS=True [Broken] ] is the maximum current that can be used to cause the transistors to operate without risking damaging them. Is it correct to state that the maximum input bias current is the maximum current that can be given to the non-inverting input as shown on this reference? http://sub.allaboutcircuits.com/images/03034.png For clarification, this is not the maximum current that the operational amplifier can handle from what is used to power the op amp, but the signal that is being amplified by the op amp. Clarification on the matter would be greatly appreciated. Some additional details are that I plan on using non-inverting op amps with negative feed back to amplify the signal given from a line level audio source in order to drive LEDs.
