The Best of Analog Dialogue

A Brief History

Analog Dialogue originated in 1967 as a means of communicating with our customers and prospects at a practical technical level. Its aim is to inform readers about new products and technologies, applications ideas, practical approaches to implementation, and to provide tutorials and other material that seems necessary to help our readers solve their problems with and through the use of our products and ideas. Rather than simply spewing forth information that might or might not be useful, the "Dialogue" in our title means that input from readers is always welcome, in the form of comments and suggestions. The undersigned has been Editor since 1969.

Through history with Analog Devices . . . Analog Devices, Inc. opened its doors for business in 1965 with the objective of satisfying the needs of a growing market for high-performance analog components. While our initial concentration was almost solely on opertional amplifier modules [Analog Dialogue's first subtitle was "A journal for the exchange of operational amplifier technology"], by 1970 we were also manufacturing analog function circuit and data converter modules ["A journal for the exchange of analog technology"]—and we had opened our first proprietary IC fab through our investment in Nova Devices, which later became Analog Devices Semiconductor.

By the end of our first decade ["A forum for the exchange of circuit technology: analog and digital, monolithic and discrete"], we had become a leader in modular data converters and had produced monolithically a variety of high-precision op amps, instrumentation amps, an analog multiplier and two highly successful IC d/a converters — the 10-bit CMOS AD7520 and the two-chip (compound monolithic integration) 12-bit AD562.

In the following decade, the IC innovations came thick and fast; in addition to a plethora of CMOS, I2L, and BiMOS converters, single-chip IC highlights of this period included the AD580 2.5-volt precision voltage reference, the AD537 V/f converter, the AD534 laser-trimmed precision analog multiplier, and the AD590 precision temperature-to-current converter. Through our acquisition of Computer Labs, we became a major player in the video converter market; and in the systems area, we offered a number of breadbox-sized systems {"A forum for the exchange of circuits and systems for measurement and control"], including the MACSYM measurement-and-control computer and the LTS-2000 series of benchtop testers ["A forum for the exchange of circuits and systems for measurement, control, and test"].

More recently, our innovative offerings included CMOS digital signal-processing building blocks ["A forum for the exchange of circuits and systems for real-world signal processing"] and a powerful, easy-to-program family of single chip DSPs, as well as a highly developed ASIC technology ["A Forum for the exchange of circuits, systems, and software for real-world signal processing"]. Our manufacturing capabilities grew to include complementary bipolar, several varieties and generations of analog BiMOS, and very-high-speed processes. The flow of new products for analog and digital signal processing continued, with high-resolution sigma-delta technology, high-speed converters; precision, current-feedback, and electrometer op amps, wideband log amps — and several series of products specifically designed for audio, automotive, disk-drive, ATE, and other markets.

As we evolve, we find, more and more, that our greatest strength has been and will be our customers — Analog Devices is looking forward enthusiastically to continuing to share products and ideas with you for at least another quarter century.
