Products and technologies

Analog Devices products include analog signal processing and digital signal processing technologies.[38] These technologies include data converters, amplifiers, radio frequency (RF) technologies, embedded processors or digital signal processing (DSP) ICs, power management, and interface products.[38]

Data converters include analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)[38] 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.[39] 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.[40] 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.[41]

The company’s data converter chips are used by National Instruments in high-precision measurement instrumentation systems.[42] 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.[43][44]

Power management products for 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.[45]

Interface products include a broad range of interface IC products offered by the company in product categories such as CAN (controller area network),[46] digital isolators,[47] level translators, LVDS, mobile I/O expander and keyboard Controller, USB, and RS-232[48]

Amplifiers includes precision and operation amplifiers,[49] instrumentation,[50][51] current sense, differential amplifiers,[52][53] audio amplifiers, video amplifiers/buffers/filters, variable gain amplifiers, comparators, voltage, other specialty amplifiers and products for special linear functions.

Analog Devices radio frequency integrated circuits (RFICs)[54][55] address the RF signal chain and simplify RF system development.[56] The company’s RF portfolio includes TruPwr(tm)[57] RMS power detectors and logarithmic amplifiers; PLL and DDS synthesizers; RF prescalers; variable gain amplifiers;[58][59][60] ADC drivers, gain blocks, LNAs and other RF amplifiers.[61]

Processors and DSP are programmable signal processing integrated circuits that execute specialized software programs, or algorithms, associated with processing digitized real-time data. Analog Devices Processors and DSPs are the Blackfin,[62] SHARC,[63] SigmaDSP,[64] TigerSHARC, ADSP-21xx and Precision Analog Microcontrollers. These make up the company's embedded processing and DSP portfolio, that are multi-DSP signal processing,[65]


Analog Devices had a line of micro-electromechanical systems (MEMS) microphones until it sold that business to InvenSense in 2013.[66] Analog Devices MEMS microphones were found in smart phones, tablet PCs, security systems, and medical applications.[67][68] ADI’s MEMS accelerometers were designed into game pad controllers by Microsoft, Logitech and Pellican.[69]



Analog Devices sells linear, mixed-signal, MEMS and digital signal processing technologies for medical imaging, patient monitoring, medical instrumentation and home healthcare.[70] The company’s precision signal-processing components and Blackfin digital signal processors are included in Karmelsonix’s Wholter, an overnight pulmonary monitor, and the Wheezometer, a personal asthmatic assessment device.[71] Accelerometers produced by Analog Devices are included in ZOLL Medical’s PocketCPR, which measures the depth of chest compressions and provides audible and visual feedback to a rescuer to allow adjustment to proper depth and to the correct rate of compression.[71]


Analog Devices develops components for safety systems, such as stability control systems and driver assistance systems, infotainment and interior applications.[72] Powertrain systems in hybrid and electric vehicles use high-precision data conversion products in battery monitoring and control systems.

Analog Devices was named number two with other suppliers including: Texas Instruments, National Semiconductor (acquired by Texas Instruments in 2011),[77] Maxim Integrated Products, Linear Technology.[78] Other competitors include: Infineon Technologies, STMicroelectronics and Intersil Corporation .[78] In 2011, Analog Devices was the third ranked analog semiconductor supplier.[79]

Analog Dialogue

In 1967, Analog Devices first published Analog Dialogue.[80] Dan Sheingold took the position of editor two years later, which he held for over four decades.[81][82] The current editor is Scott Wayne.[82] It is currently the longest-running in-house publication in the electronics industry.[83]

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.[83] 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.



In 2009, Analog Devices announced EngineerZone, an online technical support community.[84] 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.[84]


Analog Devices circuits from the lab reference circuits are engineered and tested for quick 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 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.[85]
