Transistors / Gates in AD8048 and AD8031

Hello,

I'm wondering how many transistor and/or effective gates are in the AD8048 and AD8031.

Thank you for any information might be available and happy new year

Hi Derek,

May I know why would be needing the numbers? Is it for reliability? If so, we provide FIT numbers for the Integrated circuit that you can use. See:

https://www.analog.com/en/about-adi/quality-reliability/reliability-data/wafer-fabrication-data.html

I am currently in contact with the designer for the data needed. I'll post it ASAP once available.

Regards,
Goz

Hi Gauzz,

I am modeling expected upset rates in various radiation environments. I don't need the exact number of transistors. To a factor of 10 is sufficient for my purpose. The FIT number is useful in a separate reliability analysis but for this portion I am looking for a rough estimate of transistors.

I appreciate your help.

Hi Derek,

For AD8031 the transistor count should be 98, and for AD8048 should be around that number too. Typically, General Op Amps would have 100 transistors in them.

Apologies for getting back late.

Best Regards,
Goz
