He is the inventor of many analog IC circuits, including the Brokaw bandgap reference and holds over 100 patents. He is also an IEEE Life Fellow.
Robert Adams is Technical Fellow  and manager of audio development at Analog Devices Inc. Robert holds many patents related to the audio and electronic field. He’s also a member of the IEEE and a Fellow in the Audio Engineering Society. Robert received a finalist ranking for the EDN Innovation and Innovator of the Year award in 1995.
Core Products and Technologies
Analog Devices’ product portfolio includes analog signal processing and digital signal processing technologies. These technologies include data converters, amplifiers, radio frequency (RF) technologies, embedded processors or digital signal processing (DSP) ICs, micro-electromechanical systems (MEMS) and sensors, power management, and interface products.
Analog Devices’ Data Converters include analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)  that convert electrical signal representations of real-world analog phenomena, such as light, sound, waveforms, temperature, motion, and pressure into digital signals or data, and back again. Analog Devices’ ADC and DAC ICs are used in medical systems, scientific instrumentation, wireless and wired communications, radar, industrial process control, audio and video equipment, and other digital-processing-based systems, where an accurate signal conversion is critical. Data converters account for more than 50% of ADI’s revenue. ADI’s companion amplifier ICs provide accurate, high-speed and precise signals for driving data converters and are key for applications such as digital audio, current sensing, and precision instrumentation.
The company’s data converter chips are used by National Instruments in high-precision measurement instrumentation systems. Its data converters and amplifiers are also used by scientists and researchers in project “IceCube” – an underground telescope that uses digital optical modules (DOMS) to detect subatomic particles in the South Pole.
The company’s AD9647 16-bit A/D converter operates at 250 mega samples per second, which is 25-percent faster than competitive devices.
Analog Devices precision analog microcontrollers combine precision analog functions, such as high resolution ADCs and DACs, voltage reference, temperature sensor, and a host of other peripherals, with an industry-standard microcontroller and flash memory.
Analog Devices’ micro-electromechanical systems (MEMS) and sensors address system performance parameters, such as safety, reliability, and highly precise measurements and diagnostics, in healthcare and industrial applications. Analog Devices' MEMS microphones are found in smart phones, tablet PCs, security systems, and medical applications. MEMS circuits are used in automobiles , virtual reality and simulation training systems, and high-performance high-bandwidth vibration monitoring. ADI’s MEMS accelerometers were designed into game pad controllers by Microsoft, Logitech and Pellican.
Analog Devices sells power management products to customers in the industrial, wireless infrastructure, and digital camera markets. These products support signal chain design requirements, such as dynamic range, transient performance, and reliability.

In 1967, Analog Dialogue was first published by Analog Devices. Two years later, Dan Sheingold took the reins as editor, a position he still holds today. It is currently the longest-running in-house publication in the electronics industry.
Analog Dialogue is a forum for the exchange of circuits, systems, and software for real-world signal processing and is the technical magazine published by Analog Devices. It discusses products, applications, technology, and techniques for analog, digital, and mixed-signal processing. Analog Dialogue is published monthly on the Web. The featured technical articles are also compiled in quarterly print editions.
ADI EngineerZone Community
In 2009, Analog Devices launched EngineerZone, an online technical support community for the design engineering community. EngineerZone was launched so the design engineering community (customers, prospects, partners, employees and students) can ask questions, share knowledge and search for answers to their questions in an open forum.
Analog Devices’ Circuits from the Lab reference circuits are engineered and tested for fast and easy system integration to help solve design challenges ranging from common to complex. Reference circuits are smaller, modular designs that are more broadly applicable than application-specific reference designs.
Each reference circuit is carefully documented with test data, theory of operation, and component selection decision criteria. In addition reference circuits are tailored to meet real-world system integration needs and may also include board layout schematics, CAD tools models, device drivers, and evaluation hardware.
