What are application of ic 741 opamp?
A 741 Op-amp has three distinct parts and applications. They are a differential amplifier, a voltage amplifier, and an output amplifier.
What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
Why voltage gain is high in op amp?
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
What limits output of an operational amplifier?
Feed back resistance plays the vital role of controlling output of the OPAMP. Also surrounding temperatures affects the out put of OPAMP. ANSWER: The gain drives the output to either B+ or B- minus the saturation of the output circuitry
Why input impedance of operational amplifier is infinite?
Input impedance (Zin) is assumed to be infinite to prevent any current flowing from the source supply into the amplifiers input circuitry. Infinite Input impedance is one of the Ideal Characteristics of the Op-Amp. With an assumption of Infinite Input impedance, there is no Loading on the preceeding stage to the Op-Amp (i.e. Supply.) or The Op-Amp under test does not draw any current from the I/p Supply to it's internal Circuitry.
Where is the ground on an operational amplifier?
An opamp has a ground terminal on one of the pins.
What are application of ic 741 opamp?
A 741 Op-amp has three distinct parts and applications. They are a differential amplifier, a voltage amplifier, and an output amplifier.
Who invented the opamp-741 IC?
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

How is a opamp generated?
An op-amp, or OPerational AMPlifier, is simply a pre-built transistor amplifier circuit on a self-contained integrated circuit chip (usually one chip holds multiple op-amps)

What is a difference between an operational amplifier and instrumentation amplifier and can you use one opamp to perform a same task as 3 opamp instrumentation amplifier?
An op amp is made from transistors, resistors and capacitors. It is enclosed in a "chip". A basic instrumentation amp is made of 2 op-amps. you can't have a single op-amp perform as good as a instrumentation amp, although it can perfrom the same task. An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.
Why the input resistance of opamp is high?
Because op amp consist differential amplifier and they posses high input impedance so that op-amp also posses high input impedance.
Why input impedance of operational amplifier is infinite?
Input impedance (Zin) is assumed to be infinite to prevent any current flowing from the source supply into the amplifiers input circuitry. Infinite Input impedance is one of the Ideal Characteristics of the Op-Amp.

Can an opamp be powered with 5v and 0v?
An operational amplifier can operates within those limits. [+5 volts and 0 zero ] it can operate as long as there is any kind of differential power supply withing the limits of the device itself.
Why input resistance of voltage amplifier is infinity?
For the successful amplification of the input signal the opamp should have ideally infinite input impedance . It should act like a buffer amplifierBUFFER amplifier--------------------->1.input impedance infinity2.output impedance zerothe reason is thatAny signal source will have source impedancefor the signal not to get lost and dropped across source impedance we ideally insert infinite impedance in series with it which makes the whole drop across the infinite impedance but not across the sourcesimilarly at the output zero impedance is used where in no part of the signal should be left behind in the op amp as a drop
