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.
opamps were originally designed to perform mathematical operations in electronic analog computers.

∙ 11y agoOp-amp is short for "Operational Amplifier". It is a flexible design that can be used for several applications. They are very useful as differential input stages to cancel any environmental noise that may be present on the input leads. This is important when measuring very small input signals such as that which a thermocouple produces (micro volts).

What is Op-Amp non inverting amplifier?
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.
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.
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
What is slew rate in operational amplifier?
the slew rate of an op-amp represents the maximum rate at which the output can change , no matter how large an input signal is applied the slew rate of an op-amp is specified in V/s or V/mew second.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.

What is the full form of OP-AMP?
operational amplifier
How does an op-amp differ from other amplifier suchas common emitter transistor amplifier?
A: They both use transistors. In actuality before an op amp becomes an op amp a discrete transistor made is made to provide it capabilities before it gets integrated into a substrate chip we call op amp. OP AMP have two input to work as a differential amplifier the input are bases closely match to provide virtual no voltage or current offset. Single ended amplifier has one input its reference is the signal source return.
How an op amp differs from a basic amp?
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)
What is linear op amp?
It's an op amp (operational amplifier) with a linear response, meaning that double the input means double the output.
How do you use OP-AMP as common compensator?
i know that an op amp can be used as an amplifier and a switch, but i want to have more uses of the component or device.
Distinguish between op amp and differential amplifier?
Look up "op amp" on wikipedia, there is a good drawing near the bottom right. An op amp contains a differential amplifier as the first stage, but has multiple following stages that provide amplifier near ideal characteristics of high input resistance and low output resistance (it can drive more current than a single dif amplifier stage).
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 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".

An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.
What would you use an op-amp for?
You would certainly use an op-amp or an operational amplifier, if two opposite sides which successfully met and made operations correctly with no bugs.
What is drift in op amps?
Drift is the effect of temperature on an operational amplifier (op-amp). Ideally you want zero drift (ie. op-amp is not affected by change in temperature), however this can never be practically achieved.
Why the name of op-amp ic 741?
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.
