Hi,
Yes App Note 76 does seem to apply, but it looks unclear whether or not the other note applies as they are using the two divider resistances not the innate characteristic of the error amp itself.
I took a quick look and it looks like a catch 22. If i give you a single parameter:
A=3.2
and then tell you to look in app note 43 to find out how to calculate the fish population in a given tank at a fish farm in New Jersey and app note 43 says:
Fpop=A*B*7
we can plug in A and get:
Fpop=3.2*B*7
but we still cant figure out the fish population because we were never told in reference 1 what B was.
If they state that you need to know what B is and they dont tell you what it is, then then only way to find out is to ask them. They clearly state the value in their app note for the other amplifier, so we would expect to see it clearly stated for the other amplifiers too. It could be that their chronology was that one app note came before the other, but that still doesnt explain why there is no way to easily calculate the required compensation values for the several examples they provided. They provided specific values for their several examples but they never show the way to achieve those values without referring to the app note, and the app note tells us we must know the error amp output resistance in order to calculate those specific values. So somebody made a mistake somewhere, and it doesnt really matter that much if we can extrapolate the required value from the parts already specified (this may be an option) because that much work should not be required and i seriously doubt they would want their customers to have to go through all that work when a simple spec would clear it all up immediately.
So yes you should contact them even if you can figure this out from the reference designs.
