Analog Devices designs the chips that translate between the physical world and the digital one: sensors' signals, power, radio frequencies and precise measurement all pass through its analog and mixed-signal processors. Customers spread across industrial automation, automotive, communications infrastructure and healthcare, with long product cycles that keep designs in service for a decade or more. Acquisitions of Linear Technology and Maxim Integrated deepened its catalog. High switching costs and thousands of niche parts give the business unusual pricing stability for a semiconductor company.
