What are the lackings of 741Op amp ICs?

[Shyamal]

Please tell me what are the problem of op ic.

There is absolutely no problem with the LM741. It was designed some 40 years ago and served well for some time.

Today operational amplifiers offer more flexibility in circuit design, e.g, high input resistance at low output resistance, rail to rail ability etc.

The LM741 also has a high noise level as compared to many other op amps.

Heh; at least you're not asking about the 709, the predecessor of the 741, waaaaaay back then, which suffered from potential latch-up problems. The 741 solved that and added several other enhancements (short-circuit protection and an internal lag network) which were a big deal back in the day, so let's not diss this venerable old chip too much.

Hello,

Another problem is the input range. It's not good like some other op amps. For supplies of plus and minus 15 volts we might only be able to use inputs that are only as high as plus and minus 12 volts. This could be very bad trying to work with a single power supply of 5 volts and probably wouldnt work very well at all.

Has input offset null adjustment if that's a plus for you.

The 741 opamp was designed and released 43 years ago.
It is guaranteed to work properly ONLY when its supply is plus and minus 15V. Many do not work from a supply as low as 10V.
It has a lot of hiss because 43 years ago the engineers did not know how to make an opamp with less hiss.
It has fairly good performance up to about 9kHz when slew-rate-limiting causes severe distortion (the output becomes a triangle waveform) and reduction of level to higher frequencies.

I hope it has one problem that is needed +15v and -15v.

A 741 is an lousy old single opamp. Its power supply is plus and minus 15V.
It performs poorly above only 9kHz. It cannot drive a capacitive load.

An MC34071 single, MC34072 dual and MC34074 quad opamp works with a single supply from 3V to 44V or from a dual polarity supply from plus and minus 1.5V to plus and minus 22V. It performs perfectly up to 100kHz. It can directly drive a load of up to 10nF.
