OP484 PSPICE stability

Question asked by mbart on Oct 9, 2014

Hello,

 

I simulated the stability of OP484 in follower mode (0ohms in the feedback), with no load, by opening the feedback at the ouput in AC analysis, and I measured a phase margin of 32° Instead of 45°C.

Is the model provided on the website realistic ?

How do you simulate opamp stability on Pspice, to check that I use the right method ?

 

Thanks,

 

Mathieu
