(Anyway, I think offset should be measured, slew rate also. But I think noise only refers to the AC operation, normally CMRR; PSRR are also simulated by XF sweeping the frequency. Just a litte confused) :|

Noise is always present. CMRR, PSRR must be checked. Otherwise, you will have a lot of trouble. A simple question, how can you sure you circuit only output DC signal
