Why op amp do not work in high frequency?
the op amp is a one IC which does not work at hige volteg so the IC not consumed the high frequncy
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.
Why open loop gain of op-amp is very high?
A; An ideal op amp should have infinite open loop gain so when the loop is closed with negative feedback it will be stable
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.
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 is linear op amp?
It's an op amp (operational amplifier) with a linear response, meaning that double the input means double the output.
Is IC741 is linear or not?
Yes an Op-amp
Constant current generation of linear sweep voltage using op-amp?
When using the Op-amp we get constant current generation of the linear sweep voltage.
What are the Examples for linear ic and nonlinear ic?
op amp linear ic 7805 non linear ic
How can you find the ic maker of the OP295 op amp?
OP295 was originally produced by PMI, that was the first company that produced the very low noise op-amp called OP27. Then the company was acquired by Analog Devices-
What are the active electronic components?
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
Why op-amp is called as stone?
it is a ohmic device
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.
When is the Op amp said to be working in its linear range?
it is when the feed back resistance is been connected between the inverting input and the out put
What does an LM741 micro chip do?
An LM741 is what is known as an "Operational Amplifier", or "Op-Amp" for short. Op-Amps are arguably one of the most useful electronic devices, with almost any electronic device containing at least one in some form or another. Exactly what an Op-Amp does depends on the circuit it is in, however in general, an Op-Amp takes an input signal and boots it up to a higher level. One application would be a microphone pre-amp, where an Op-Amp would take the low-voltage input from the microphone and boot it up to a level that the power amp can use.
When is the Op-amp said to be working in its linear range?
When the slope of the output/input is a straight line, before the knee point. The knee point is where the slope dramatically changes from the linear region to saturation.
Is it possible to use op amp in open loop mode?
Yes, but it is not very useful in open loop mode. In open loop mode, unless you happen to be very lucky (as in extraordinarily lucky, meaning you won't be) the output will be pegged to one of the two rails. The op-amp will be operating in saturated mode instead of linear mode, and its response time will suffer. You could also damage the op-amp.
