I have the AD8276 model in LTSpice running a noise analysis. The results are far above expected from datasheet. Could I please get some help with this?
Can you try the attached model?
The noise models are:

Similar for the AD8278
I will check with the spice model developer of this part for information and get back to you.
Has this issue been resolved? I'm facing a similar problem with the AD8278.
Sorry for the delay but the spice model issue is not yet resolved. We are trying to fix this. We will update you as soon as we finish the fix.
Would be nice to get an updated SPCE model, the noise is still the same...
