Forum Post: TINA - INA111, How to simulate noise behavior (differential mode and common mode).

Hello,

I am trying to use TINA to simulate noise behavior of the INA111 (differential mode and common mode), but I can't figure out how to do it?  Is it possible?

I need to see the noise rejection performance.  I tried to use a DC V-source to simulate a 0~20mV signal (DC), and then added an sinusoid 0~5mV V-source to simulate added differential noise. But that approach didn't work.

Any suggestions?

Thank you!
