I was adding this new FDA to my parametric tables and noticed this common mistake, Rejection Ratio is a positive number, this is a plot of rejection,
Also, where is the Aol plot?

Ok, the model appears to be showing a 240Mhz GBP,
Pretty darn good match to the 245Mhz in the datasheet,
And before I close this file and move, on here is the gain of 1 LG plot (NG of 2). That 112MHz LG=0dB xover with 64deg phase margin is almost a perfect Butterworth,
Where this plot would predict a closed loop BW of 1.55*112Mhz = 174Mhz F-3dB, very close to the specified 187MHz number,
This comes from this article,

Hi Michael,
Thanks for bringing these points to our attention. We are working on getting these corrected now. I will update when these changes are made.
Thanks,
Nick
