I was looking for some parts in my garage today and I found a bag of 50 AD42020-1 IC's. I can't find a datasheet ( about 30 years old ). Does anyone know what they are, or have a datasheet?
See pic.
I wonder why I kept them.
I think that they were 175 to 200MHZ vfb opamps that ran from +-6V supplies.
I still am looking for a datasheet.

I found this part in the Fluke 6080A Service Manual, it is an Analog Multiplier.
