**Other Parts Discussed in Thread:**OPA355

Hello this is seongmun kim

nowaday, i am running to simulation about noise analysis.

but example noise information in macro is not correct for analysis.

can i share the inforamtion about noise component for OPA355, 380?

each information of noise modeling for opamp is difference.

and some product has a different behavior on noise current density as OPA355 and OPA 227. in case of it, how can i get the noise information by macro viewer?

i uploaded noise information on curent noise source of opa355.
