The company was founded by two MIT graduates, Ray Stata and Matthew Lorber in 1965. The same year, the company released its first product, the model 101 op amp, which was a hockey-puck sized module used in test and measurement equipment. In 1967, the company published the first issue of its technical magazine, Analog Dialogue.

In 1969, Analog Devices filed an initial public offering and became a publicly traded company. Ten years later, the company was listed on the New York Stock Exchange.

In 1973, the company was the first to launch laser trim wafers and the first CMOS digital-to-analog converter. By 1996, the company reported over $1 billion in company revenue. That same year, Jerald Fishman was named President and CEO, a position he held until his death in 2013 (see below).

In 2000, ADI's sales grew by over 75% to $2.578 Billion and the company acquired five companies including BCO Technologies PLC, a manufacturer of thick film semiconductors, for $150 million.
In January 2008, ON Semiconductor completed the acquisition of the CPU Voltage and PC Thermal Monitoring Business from ADI., for $184 million.

By 2004, ADI had a customer base of 60,000 and its portfolio included over 10,000 products.

In July 2016, Analog and Linear Technology agreed that Analog would acquire Linear in an approximately $14.8 billion cash and stock deal.
