(Include date or date range in title. Example: “Alternating Current Electrification, 1886”) Please provide a plaque citation in English summarizing the achievement and its significance. Text absolutely limited by plaque dimensions to 70 words; 60 is preferable for aesthetic reasons. NOTE: The IEEE History Committee shall have final determination on the wording of the citation. Names of living persons are not normally used in citations. Exceptions to this are cases where the person's name is linked to the achievement itself (e.g. the Lempel-Ziv algorithm, Maxwell's Equations, etc.) or where the person's name is so widely recognizeable to the general public that it makes sense to use it. When used, the names should be the names of the engineers, scientists, or technologists who actually made the achievement, rather than managers or executives. For more information and suggestions about writing milestone citations, please visit Helpful Hints on Citations, Plaque Locations. In what IEEE section(s) will the milestone plaque(s) reside? Please specify the IEEE Organizational Unit(s) which have agreed to sponsor the Milestone, and supply name and contact information for the senior officer from those OU(s). Sponsorship has three aspects: 1) Payment for the cost of the plaque(s), 2) Arranging the dedication ceremony, and 3) agreeing to monitor the plaque and to let IEEE History Center staff know in case the plaque needs to be moved, is no longer secure, etc. Number 3 must be done by the IEEE Section(s) in which the plaque(s) is located, but aspects 1 and 2 can be done by any IEEE Organizational Unit, and they need not be the same one. Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Please include coordinates in decimal format rather than degrees. What is the intended site(s) of the milestone plaque(s) relation to the achievement? The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque. Also, please Describe briefly the intended site(s) of the milestone plaque(s). (e.g. Is it corporate buildings? Historic Site? Residential? Are there other historical markers already at the site?) Are the original buildings extant? Please provide the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. How is the intended plaque site protected/secured, and in what ways is it accessible to the public? If visitors to the plaque site will need to go through security, or make an appointment, please give details as well as the contact information visitors will need in order to arrange to visit the plaque. Who is the present owner of the site(s)? In the space below, please describe in detail: the historic significance of the achievement, its importance to the evolution of electrical and computer engineering and science, its importance to regional/national/international development, its benefits to humanity, the ways the achievement was a significant advance rather than an incremental improvement of existing technology. The material submitted here will constitute the main descriptive article on the ETHW website for readers to learn about the milestone. Space is unlimited, and detail is encouraged. Most milestones require 1000 to 1500 words of support, however there is no word limit. The article should be readable by a wide audience that includes practicing engineers, scholars of history, and the general public. Some examples of the text of good milestone articles are First Radio Astronomical Observations Using Very Long Baseline Interferometry] and G3_Facsimile International Standardization of G3 Facsimile (Do not worry about the formatting of the page, IEEE History Center Staff will do that afterwards.) What is the historical significance of the work (its technological, scientific, or social importance)? In April of 1981, Jim Naylor, William J Lillis, Anthony D. Wang, and Robert L. White from Burr-Brown Research Corporation (Tucson, AZ) which later on become part of Texas Instruments, Inc.; filed 2 US patents 4,381,497 and 4,423,409 on a monolithic Digital to Analog converter design. Later on Jim Naylor wrote a paper in 1983  on PCM53/DAC700 - The World's First Monolithic 16-bit DAC that the TI Burr-Brown team designed. Paul Prazak has presented the paper at the WESCON 82. This product played a key role in transforming the music industry from analog vinyl disc to Digital Compact Disc and was a monumental change. The PCM53/DAC700 is the World's First Monolithic 16-bit DAC. Designed by Jimmy Naylor and TI / Burr-Brown data converter design team , this product played a key role in transforming the music industry from analog audio tapes and Vinyl long Play Discs (LPs) into digital audio Compact Discs. This 16bit DAC was designed in to almost all major manufacturers of CD players when the Compact Disc Player was emerging as an superior Digital Audio apparatus and led TI / Burr-Brown to dominate the digital audio data converter market with more than 80% share for several years. The TI burr brown DACs was mentioned in the movie “The Italian Job”. This unique monolithic chip and its fundamental achievement together with the technical advances in Audio and Speech processing, digital signal processing, which occurred in the 1970s and 1980s  resulted in digital audio overtaking analog audio and spawning a new digital audio industry that we still expanding today. What obstacles (technical, political, geographic) needed to be overcome? To reduce a multichip hybrid converter design to a single chip, several obstacles had to be overcome in the late 1970’s or early 1980’s: Power consumption changes on a single chip will cause thermal gradients that affect temperature sensitive components introducing offset, gain, and/or linearity errors. Since thermal gradients on the chip surface take a few hundred microseconds to stabilize after a power change, the settling time of the DAC output could be adversely affected. This phenomenon is sometimes referred to as a thermal settling “tail.” Minimizing the die size precluded the use of large capacitor values that is common in a hybrid design, for the compensation of amplifiers or for suppressing switching transient. To realize the new single chip monolithic DAC, and holding the die size to less than 20000 square mils to minimize the cost per die, required an innovative process technology. Rather than using a conventional 40 V bipolar process used for many analog circuits, a thinner epi process yielding 20 V BVCEO transistors was chosen. This saved considerable die area as typical transistor geometries are approximately 50 percent smaller. What features set this work apart from similar achievements? For the first time, a complete 16-bit monolithic DAC has been integrated into a single chip with all the components necessary for a high performance Digital to Analog converter. Up until this point all 16-bit DACs were multi-chip hybrids that are not functionally complete because external components must be added and they were very costly to build. When Sony and Philips were designing the Digital Audio players, there were three fundamental problems that needed to be solved: 1) A medium that could store the amount of information needed for high fidelity audio. They started with digital tape, but settled on the compact disc (CD) format. 2) Lowering the cost of the read mechanism (laser) to read the CD. 3) A low cost, high performance DAC to play back the music! TI / Burr-Brown’s design team were already working on a monolithic DAC for industrial markets, but we really stepped up the pace and were first to market. The differential linearity laser trim algorithm made the DAC Supporting texts and citations to establish the dates, location, and importance of the achievement.
