[sdiy] Op-Amp with good PSRR

[Tony Rolando]

Hello, I am in need of an dual op amp that has a low Power Supply 
Rejection Ration (PSRR). A slow op amp is fine. Right now I am using a 
LM358, and the problem I am having is that a best case scenario the 
LM358 works good, but several of the LM358 do not. The data sheet shows 
the spec as Typical 100db and Minimum of 60db for LM358.

Does anybody have a suggestion for something I could drop i place of the 
LM358 that might have better rejection?

Thanx,

Tony Rolando
