AD9276 page 23,
The datasheet does have an error. For this example the gain is 8 so A/2 is 4. The parallel resistance of 200-ohm and 15,000-ohm results in 197-ohm and a gain error of 0.06dB. I marked up the datasheet as reference.
It looks like there may have been a problem with your post. We only received the first three words. Would you mind re-posting your full question so someone here can provide assistance?

Sorry. Last time I can't describe clear.
I want known how to calulate AD9276 impedance. I studied AD9276 datasheet at page 23. Pls see attach file.
Thanks a lot!
Thanks for providing more information. I have moved this question the the High-Speed ADCs community. You should be able to get some support there.
