Analog Devices has approximately 100,000 customers in the following industries: communications, computer, instrumentation, military/aerospace, automotive, and consumer electronics applications.

## History

The company was founded by two MIT graduates, Ray Stata and Matthew Lorber in 1965. The same year, the company released its first product, the model 101 op amp, which was a hockey-puck sized module used in test and measurement equipment. In 1967, the company published the first issue of its technical magazine, Analog Dialogue.
In 1969, Analog Devices filed an initial public offering and became a publicly traded company. Ten years later, the company was listed on the New York Stock Exchange.
In 1973, the company was the first to launch laser trim wafers and the first CMOS digital-to-analog converter. By 1996, the company reported over $1 billion in company revenue. That same year, Jerald Fishman was named president and CEO, a position he held until his death in 2013 (see below).
In 2000, Analog Devices's sales grew by over 75% to $2.578 Billion and the company acquired five companies including BCO Technologies PLC, a manufacturer of thick film semiconductors, for $150 million.
In January 2008, ON Semiconductor completed the acquisition of the CPU Voltage and PC Thermal Monitoring Business from Analog Devices., for $184 million.
By 2004, Analog Devices had a customer base of 60,000 and its portfolio included over 10,000 products.
In 2012, the company led the worldwide data converter market with a 48.5% share, according to analyst firm Databeans. Also, the company moved its listing from the NYSE to Nasdaq effective April 2, 2012.
In July 2016, Analog and Linear Technology agreed that Analog would acquire Linear in an approximately $14.8 billion cash and stock deal.
In July 2020, Analog agreed to acquire Maxim Integrated in an all stock deal that values the combined company at $68 billion.

## Products and technologies

Analog Devices products include 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, power management, and interface products.
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 neutrino telescope that uses digital optical modules (DOMS) to detect subatomic particles in the South Pole.
Power management products for customers in the industrial, wireless infrastructure and digital camera markets support signal chain design requirements, such as dynamic range, transient performance, and reliability.
Interface products include a broad range of interface IC products offered by the company in product categories such as CAN (controller area network), digital isolators, level translators, LVDS, mobile I/O expander and keyboard controller, USB, and RS-232.
Amplifiers includes precision and operational amplifiers, instrumentation, current sense, differential amplifiers, audio amplifiers, video amplifiers/buffers/filters, variable gain amplifiers, comparators, voltage, other specialty amplifiers and products for special linear functions.
Radio frequency integrated circuits (RFICs) address the RF signal chain and simplify RF system development. The company's RF portfolio includes TruPwr RMS power detectors and logarithmic amplifiers; PLL and DDS synthesizers; RF prescalers; variable gain amplifiers; ADC drivers, gain blocks, LNAs and other RF amplifiers.

## Analog Dialogue

In 1967, Analog Devices first published Analog Dialogue. Dan Sheingold took the position of editor two years later, which he held for over four decades. The current editor is Bernhard Siegel. 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.

## Communities
### Community

In 2009, Analog Devices announced EngineerZone, an online technical support 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. EngineerZone currently hosts over 100 English forums to discuss ADI products and share projects with other engineers. Members are encouraged to self-serve by searching their rich knowledge base of FAQs and to respond to fellow member's threads. EZ China is also available for members seeking support in simplified Chinese.

### Resources

Analog Devices offers reference circuits through its Circuits from the Lab program. These 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.
