What are your supply rails? The LM747 will tolerate 22V supplies, which is more than most opamps will take.

The AD8513, AD8674 and OP470 may be worth a look as they all have better performance. I don't know about Mil spec though.

Bryan,

I wish you would have gotten a name so I could track this down further.  Was it a local field office

or an office in Norwood?   Which department?  That is certainly unacceptable behavior.

I was the product line apps engineer for the ADA4627-1.
