Nova Devices acquired, adding technology to the design and manufacture of linear semiconductor products. 1972 ADI publishes its first technical handbook, Analog - Digital Conversion Handbook. Authored by ADI's engineers, it is the first authoritative text on data conversion and immediately becomes an industry standard. The AD520 is introduced, the world's first monolithic instrumentation amplifier. Process allows on-chip digital logic, eliminating external logic chips.
Technology improves performance and achieves better production yields.
1977 ADI patents and introduces the AD590 semiconductor temperature sensor. This revolutionary sensor quickly becomes an industry standard. Ray Stata spearheads formation of the Massachusetts High Technology Council to promote a political environment that is more conducive to attracting and retaining good engineers and other technical professionals. ADI acquires Computer Labs of Greensboro, NC to enhance ADI's high-speed converter product line. 1979 ADI's stock is listed on the New York Stock Exchange.
