These helped me build Intelligent Instruments in the 80s. Intersil was with GE earlier, innovators of   advanced CMOS before anybody else. They made the smartest chips when the Microprocessors were being examined Skeptically by engineers. (At that time Microprocessors needed many support chips and consumed huge power only later CMOS uC came).

Today i found out that another company of that time called Datel is back, it was first a part of GE like Intersil then went to Murata now after decades it is back home.

“Datel was established in 1970 and has been a long time leader in providing high precision data acquisition components, including data converters, power supplies, DC-DC converters, and digital panel meters. ”
