Texas Instruments Incorporated is a global analog and digital semiconductor IC design and manufacturing company. In addition, to analog technologies, digital signal processing and microcontroller semiconductors, it designs and manufactures semiconductor solutions for analog and digital embedded and application processing. The company operates through four business segments: Analog segment, Embedded Processing segment, Wireless segment and Other segment. The Analog segment semiconductors change real-world signals such as sound, temperature, pressure and images by conditioning them, amplifying them and often converting them to a stream of digital data that can be processed by other semiconductors, such as digital signal processors. Its product portfolio includes high-volume analog and logic, high-performance analog and power management. The High-volume analog and logic products include specific applications and custom products. The High-performance analog products include standard analog semiconductors, such as amplifiers, data converters and interface semiconductors. The Power management products include both standard and custom semiconductors that help customers manage power in any type of electronic system. It designs and manufactures power management semiconductors for both portable devices, such as handheld consumer electronics, laptop computers and cordless power tools and line-powered systems, such as computers, digital TVs, wireless base stations and high-voltage industrial equipment. The Embedded Processing segment products include digital signal processing and microcontrollers. Digital Signal Processing performs mathematical computations almost instantaneously to process and improve digital data. Microcontrollers are designed to control a set of specific tasks for electronic equipment. It manufactures and sells standard and catalog Embedded Processing products used in many different applications and custom Embedded Processing products used in specific applications, such as communications infrastructure equipment and automotive. The Wireless segment designs, manufactures and sells semiconductors that enable connectivity through means other than the cellular network, such as Bluetooth devices and Wi-Fi networks. The Other segment includes smaller semiconductor product lines and sales handheld graphing and scientific calculators. The company was founded in 1930 by Cecil H. Green, Patrick Eugene Haggerty, John Erik Jonsson and Eugene McDermott and is headquartered in Dallas, TX.
