this link is for triangular wave generation using opamp. they provides a circuit file for wave generation n also the circuit diagram. How can i know abt the opamp model they r using for the simulation.. can u guys help !!!

thanx

The spice file with the description of the opamp model used (.subckt opamp1) is at the end of the document.

yes i saw that subckt but is there a way to know which opamp model is this? say uA741 or TL082 etc

No, the model does not reflect the properties of any commercial part.
It is just a simple behavioural description of some of the most important opamp parameters (gain with one pole, input/output impedance, supply rail limitations).
