OPA2830: Device technology and transistor count

Part Number: OPA2830
Other Parts Discussed in Thread: OPA830, OPA2652, OPA2822, OPA2677

Hello, 

I am carrying out some reliability analysis on the OPA2830 and am having trouble finding information about the technology the chip was made with and am also curious about the rough number of transistor on-board, to a factor of 10. I realize the second bit of information tends to be proprietary and is why I'm asking for just a rough number. 

Thank you for any information you might have.

    Hello Nick,

       I will have to look into finding this information for you. I am unsure how much I can disclose for the second part of your question for the reasons you have already mentioned, but I should have an update for you by the end of this week. 

    Thank you,

    Sima

    Morning Nick, 

    This OPA2830 is part of a high speed amplifier family on CBC10 - (Complementary Bipolar with CMOS 10GHz). Approximate 14V breakdowns with vertical NPN and PNP with thin film trimmable resistors. As a dual of the OPA830, it would have approximately 50transistors per amplifier or no more than 100 for the dual.

    I had written a feature article on this process back in the 1999 time frame, but cannot find it now (online) - I did find this history by Steve Taranovich where it is mentioned as the process for the OPA2652 -

    https://www.edn.com/analog-back-to-the-future-part-two/

    yes, the first 3 products on that process were the 

    OPA2652 (dual VFA)

    OPA2822 (dual low noice VFA)

    OPA2677 (dual CFA xDSL line driver).

    Thanks a ton, Michael, I think this answers all of my questions.
