What is the OPAMP?

Could anyone help me about the OPAMP meaning.And How use ?

MON,

Take a look here:

Re: What is the OPAMP?

It is a device that amplifies a differential signal and can give you a gain from unity to several hundreds for analog signals.
 

Re: What is the OPAMP?

I highly recommend this paper form Ti: **broken link removed** 8)

Moved from Professional hardware to elementry electronics

Please post in appropriate forum :wink:

What is the OPAMP?

OpAmp is the amplifier that has the characteristic close to the ideal amplifier. The ideal amplifier has infinite gain, infinite input impedance and zero output impedance.
 

Re: What is the OPAMP?

OPAMP=operational amplifier,you can read <CMOS analog circuit design>(by Allen adn Holberg)in details.
 

Re: What is the OPAMP?

The op-amp is basically a differential amplifier having a large voltage gain, very high input impedance and low output impedance. The op-amp has a "inverting" or (-) input and "noninverting" or () input and a single output. The op-amp is usually powered by a dual polarity power supply in the range of 5 volts to 15 volts
 

Re: What is the OPAMP?

I would argue that the opamp has characteristics that are often underutilized. Typically, high gain is the underlying use. If you don't already know, gain alows you to take a small difference and produce a large difference. This is helpful because a large signal is more useful. A large signal can drive a speaker, it can be digitized where a small signal can't be digitized because the ADC is simply setup with larger voltage levels because it needs the biasing of the transistors.
 

Re: What is the OPAMP?

The opamp was originally designed to carry out mathematical operations in analogue computers, such as bombsights, but was soon recognised as having many other applications.
The opamp usually comes in the form of an 8 pin integrated circuit, the most common one being the type 741.

It has two inputs and one output.
The input marked with a - sign produces an amplified inverted output.
The input marked with a + sign produces an amplified but non inverted output.

The opamp requires positive and negative power supplies, together with a common ground.
Some circuits can be designed to work from a single supply.

If the two inputs are joined together, then the output voltage should be midway between the two supply rails, i.e. zero volts.
If it is not, then there are two connections for adding a potentiometer, to remove this OFFSET.
 

Re: What is the OPAMP?

OPAMP stands for operational amplifier...........

Search elektroda for more help and material about OPAMP......

I saw a pdf version of ebook with title OPAMPs for everyone at elektroda....so do check it.........it will help u..:)
 


Re: What is the OPAMP?

opamp means an operational amplifier..
its a high gain open loop differential amplifier..
 

What is the OPAMP?

op-amp stands for operational amplifier. As per the name it peforms the normal amplification funcation as well as LOGICAL functions also. lkie op-amp works as a adder, substractor, integrator, differtentor etc.
as per theory it has infinite voltage gain but proctically it is unity to several hundreds for input signals. more ever the high bandwidth is also important factor. Means it can produce the high output for almost all frequency range input signal
 

What is the OPAMP?

Opamp is nothing but a differential amplifier with high gain..its name because it can do multiple operation like differentiation,integration,summation,subtraction etc thats why called operational amplifier.

Click to expand...

OPAMP means operational Amplifier... The name comes mainly because mathematical operations can be done.................
 

What is the OPAMP?

kinda amplifier which is mostly used to do some mathematical operations simply so why it is operational amplifier..
 

Re: What is the OPAMP?

An operational amplifier, usually referred to as an op-amp for brevity, is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single output. In its ordinary usage, the output of the op-amp is controlled by negative feedback which, because of the amplifier's high gain, almost completely determines the output voltage for any given input.
