The data sheet list 4 valid PNs for this device in the SOT-23 package: OPA703NA/250, OPA703NA/3K, OPA703NA/250G4 & OPA703NA/3KG4. Nowhere on the website or in the data sheet can I find an explanation of the "G4" suffix. We are trying to fill demand and one version is available and the others aren't so I need to verify that the G4 parts are interchangeable with the non-G4 parts, please. For my own curiosity, I'd like to understand what the suffix signifies, since I can't imagine extra PNs were added for no reason. Regards - Cory Gill
