Hello,

What is the clear difference between with LM2904DR and LM2904DRG3

Is it only the number of certified AT site?

Is it okay to understand that LM2904DRG4 and LM2904DR made at same factory are same?

Hello Yoshihiko,

Per the order and quality information, the difference is lead finish.

Hey Nakayama-san,

Similar to the post shared by Kai, there is no difference in these devices:

Overall, you will see devices that have G4 with the lead finish NiPdAu, G3 will indicate the lead finish of SN, and where there is not G3 or G4 the lead finish will either be NiPdAu or Sn (see reference here).

However in this case both of these devices are NiPdAu, so there is no difference between these devices.

Also referenced in this e2e "The G4 refers to 'green' (eco friendly) materials" https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1065418/lm2904-meaning-of-silk-screen-printing/3941723?tisearch=e2e-sitesearch&keymatch=LM2904%2520G4#3941723

All the best,
Carolina
