hi!

But as i know the power supply of opamp741 is 15V. I need 3.3 V power supply
opamp.

The companies that make op amps also have models on their web sites. You will have to carefully look at the model descriptions. Some are simplified for faster simulations and do not include items such as accurate output signal swing limits, input bias currents, input offset voltages, etc.

Hi,

A lot of compagnies model are also available on 0rcad's pSpice site.
