Hello Roger,


Answers here and elsewhere do not convince me:

3) Quantity. Instrumentation amps have a potentially much larger
market, specificaaly they could be used to improve most designs where
diff amps are used.


Like where? I have used diff amps in designs that went into production
but I have never used instrumentation amps on any released product.
There was no need to.

Still missing the point :-(

If a precision instrumentation amp cost pretty much what a precision
diff amp does then there would seem little point having both in a
product range.

So that rules out "quantity" as a factor.
