A lousy old 741 opamp design is 46 years old. The opamp has such poor specifications that it should be buried.
An opamp can be used in thousands of circuits. Look at OPAMP CIRCUITS in Google Images (but it has no oscillators).

The lousy old 741 opamp design is 46 years old. It works poorly above 9kHz.
Audio opamps work well up to 100kHz and higher. There are many of them available in The West.

The + input of IC1 is held at +12V
The - input of IC1 will not go higher than +12V, so there is a good change that IC1 output will be permanently high.
I would have put a potentiometer (maybe 100k Ohms) on the + input of IC1 to provide a variable reference voltage.
I am assuming that IC1 is a 741 op-amp or similar?

can you suggest me nice project with the help of 741 op-amp....currently i m making a radio using 741 op-amp.....still can u help me for another...with circuit should not be very complex.....simple & easily implemented....
if you can...
thank you very much....sir....u can also suggest topic on LM380 audio amplifier....or 555 ic tim

Power OPs are basically available. Optimal respectively suitable solution depends on your application. A 741 with a current booster (npn and pnp power transistors) may be a simple solution without depending on special parts.

please show me the circuit of "Two decade BJT-OP AMP cascade inverting voltage amplifier".
only one BJT,One OP AMP UA 741 and a single power supply of 12v must be used.
a 10K ohm load and an input signal will be connected via capacitors to the amplifier.The maximum voltage gain is about -500. Input impedance is about 600 oh
