George,

Unfortunately TI does not offer any other envelope modulation/tracking power converters.

Thanks,
Aaron

Hi Aaron,
This is a part that we have been buying for year LM329DZ/NOPB I have just been informed that it has been discontinued. Does TI have a replacement part?

Thank you,

Hi George,

The closest we have is the LM4040-N which can do 5V or 10V.
If you need the 6.9V then I would use the LM4041-N w/ external resistors as it can be adjusted to 6.9V with similar specifications.

Can you tell me more about the application?

Hi Marcoo,

Thank you for the information. Can you please advise if either of these parts are available in a TO-92 package?

Thank you,

Hi Marcoo,

Before I go back to engineering, could you advise me on what the full partno of either LM4040 or LM4041 would be for the cross to the LM329DZ

Thank you,

Hi George,

I would recommend the LM4041CIZ-ADJ/NOPB
This is the LM4041-N ADJ in C grade. Then the engineers just need 2 external resistors to get the 6.9V so the rest of the system does not change.
