Description of Business	Description of Business Analog Devices, Inc. (Analog Devices or the Company) is a world leader in the design, manufacture and marketing of a broad portfolio of solutions that leverage high-performance analog, mixed-signal and digital signal processing technology, including integrated circuits (ICs), algorithms, software, and subsystems. Since the Company's inception in 1965, it has focused on solving the engineering challenges associated with signal processing in virtually all types of electronic equipment. The Company's signal processing products play a fundamental role in converting, conditioning, and processing real-world phenomena such as temperature, pressure, sound, light, speed and motion into electrical signals to be used in a wide array of electronic devices. As new generations of applications, such as the Internet of Things, evolve, new needs for high-performance analog signal processing and digital signal processing (DSP) technology are generated. The Company focuses on sensing, measurement, and connectivity challenges that apply to a diverse set of customers and markets. The Company combines data converters, amplifiers and linear products, radio frequency (RF) ICs, power management products, sensors based on micro-electro mechanical systems (MEMS) technology and other sensors, and processing products, including DSP, micro controllers and other processors, into technology platforms that the Company adapts to specific customer and market needs, leveraging its engineering investment across a broad base of customers.
