Thank you, Jennifer, and good afternoon, everyone. Thanks for joining Analog Devices Third Quarter Fiscal 2015 Earnings Conference Call. You can find our press release and relating financial schedules on our Investor page at investor.analog.com.
Now before we begin, I want to call your attention to 2 new items. Number one is about a change around the timing of our future earnings conference calls, and number two is about increasing the level of information we provide investors.
So first, starting next quarter, which will be our fiscal fourth quarter, we are going to move our earnings conference call to the morning. After speaking with many investors and analysts, we believe a morning call is a more convenient time for all stakeholders. As a result of this change, starting November 24, 2015, which is our fourth quarter 2015 earnings call, and for every quarterly earnings conference call thereafter, we will issue our earnings release at 8 a.m. Eastern Time. And the earnings conference call will take place 2 hours later at 10 a.m. Eastern Time.
Secondly, we have introduced an investor slide deck, which we call the investor toolkit. And this slide deck or toolkit has been designed to provide investors with even more clarity around our results. We've posted the toolkit on our Investor page at investor.analog.com, and this is something we plan to prepare and post every quarter through our website.
So let's get back to today's call. As usual, I'm joined by ADI's CEO, Vincent Roche; and ADI's CFO, Dave Zinsner. Our agenda for today's call will be as follows: First, I will provide a brief overview of our third quarter results, then Dave will review our financial performance in the third quarter and provide our business outlook for the fourth quarter. And finally, Vince will capstone the scripted portion of today's call with his closing remarks.
Now as is customary, after our prepared remarks, we'll open up the lines for Q&A. So please note the information we're about to discuss today, including our objectives and outlook, includes forward-looking statements. Actual results may differ materially from these forward-looking statements as a result of various factors, including those discussed in our earnings release and our most recent 10-Q. These forward-looking statements reflect our opinion as of the date of this call, and we undertake no obligation to update these forward-looking statements in light of new information or future events.
Our comments today will also include non-GAAP financial measures, which we have reconciled to their most directly comparable GAAP financial measures in today's earnings release, which we've posted on our IR page at investor.analog.com.
So with all that behind us, let's get started. So as you've likely seen from our press release, ADI had another very strong performance in the third quarter of 2015. The combined power of our franchise, our commitment to innovation, the diversity of our business and our continued strong execution delivered results that were at the very high end of our guidance range.
Revenue in the third quarter of $863 million increased 5% sequentially, and 19% year-over-year, once again, establishing a new high watermark for ADI. By end market, the industrial and automotive sectors were about in line with our expectations, while consumer revenue exceeded our plan and more than offset the impact from a weak wireless infrastructure CapEx environment.
Now I would like to give you some color on our performance by end market during the third quarter. At 44% of total sales, our highly diversified industrial business was about even to the prior quarter. Strength within industrial verticals, such as aerospace and defense, and the renewable energy sector, was offset by weaker industrial automation sales. End customer bookings in the industrial market were generally stable during the quarter.
We believe that there's currently a good match between supply and demand in our industrial business, which is largely serviced through distribution, where we recognize revenue in all regions of the world on a sell-through basis.
Now turning to automotive. After growing 13% sequentially in the second quarter, automotive decreased 7% in the seasonally slower third quarter and represented 15% of our total sales. At the current quarterly run rate, automotive represents a $500 million-plus annual business for Analog Devices.
Revenue from our hundreds of communications infrastructure customers at 16% of sales declined 22% sequentially, which was the third consecutive quarter of sequential revenue declines in the sector. Revenue from wireline customers represented about 1/3 of our communications infrastructure sales, and was approximately flat to the prior quarter.
A weaker-than-planned wireless infrastructure market in North America and China, combined with customer inventory drawdowns, impacted our performance in the third quarter. We believe that current wireless infrastructure revenue run rates for ADI are artificially low, and that our strong position in this sector will allow us to recover rapidly when this market snaps back, as it usually does without much notice.
Consumer revenues at 24% of sales grew significantly over the prior quarter. While prosumer audio/video was stable sequentially, portable applications continue to drive our consumer growth. Our strategy in consumer remains strikingly consistent: we participate in those applications where we can leverage existing core technology to solve our customers' toughest challenges, where we believe our innovation is sustainable and where our technology makes a meaningful difference to the user experience. And by leveraging existing core technology, we further increase the ROI on our R&D investment.
So now I'd like to turn the call over to Dave for details of our financial performance in the third quarter. With the exception of revenue and other expense, Dave's comments on third quarter 2015 P&L line items will exclude special items, which in the aggregate total $30 million. When comparing our third quarter performance to our historical performance, special items are also excluded from prior quarter results and year-over-year results. And reconciliations of these non-GAAP measures to their comparable GAAP measures are included on Schedule E in today's earnings release. So with that, Dave, it's all yours.
