Products and technologies
Analog Devices products include analog signal processing and digital signal processing technologies.[8] These technologies include data converters, amplifiers, radio frequency (RF) technologies, embedded processors or digital signal processing (DSP) ICs, power management, and interface products.[8]
Data converters include analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)[8] 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.[9] 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.[10] 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.[11]
The company's data converter chips are used by National Instruments in high-precision measurement instrumentation systems.[12] 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.[13][14]
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.[15]
Interface products include a broad range of interface IC products offered by the company in product categories such as CAN (controller area network),[16] digital isolators,[17] level translators, LVDS, mobile I/O expander and keyboard controller, USB, and RS-232.[18]
Amplifiers includes precision and operational amplifiers,[19] instrumentation,[20][21] current sense, differential amplifiers,[22][23] 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)[24][25] address the RF signal chain and simplify RF system development.[26] The company's RF portfolio includes TruPwr[27] RMS power detectors and logarithmic amplifiers; PLL and DDS synthesizers; RF prescalers; variable gain amplifiers;[28][29][30] ADC drivers, gain blocks, LNAs and other RF amplifiers.[31]
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,[32] SHARC,[33] SigmaDSP,[34] TigerSHARC, ADSP-21xx and Precision Analog Microcontrollers. These make up the company's embedded processing and DSP portfolio, that are multi-DSP signal processing,[35]
Historical
Analog Devices had a line of micro-electromechanical systems (MEMS) microphones until it sold that business to InvenSense in 2013.[36] Analog Devices MEMS microphones were found in smart phones, tablet PCs, security systems, and medical applications.[37][38] ADI's MEMS accelerometers were designed into game pad controllers by Microsoft, Logitech and Pellican.[39]
