Segment Reporting [Abstract]

Segment Information

Segment Information

The Company operates and tracks its results in one reportable segment based upon the aggregation of five operating segments. The Company designs, develops, manufactures and markets a broad range of integrated circuits. The Chief Executive Officer has been identified as the Chief Operating Decision Maker. The Company has determined that all of the Company's operating segments share the following similar economic characteristics, and therefore meet the criteria established for operating segments to be aggregated into one reportable segment, namely:

•The primary source of revenue for each operating segment is the sale of integrated circuits.

•The integrated circuits sold by each of the Company's operating segments are manufactured using similar semiconductor manufacturing processes and raw materials in either the Company’s own production facilities or by third-party wafer fabricators using proprietary processes.

•The Company sells its products to tens of thousands of customers worldwide. Many of these customers use products spanning all operating segments in a wide range of applications.

•The integrated circuits marketed by each of the Company's operating segments are sold globally through a direct sales force, third-party distributors, independent sales representatives and via our website to the same types of customers.

All of the Company's operating segments share a similar long-term financial model as they have similar economic characteristics. The causes for variation in operating and financial performance are the same among the Company's operating segments and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) product differentiation and (iv) size of market opportunity. Additionally, each operating segment is subject to the overall cyclical nature of the semiconductor industry. Lastly, the number and composition of employees and the amounts and types of tools and materials required for production of products are similar for each operating segment.

Revenue Trends by End Market

The following table summarizes revenue by end market. The categorization of revenue by end market is determined using a variety of data points including the technical characteristics of the product, the “sold to” customer information, the “ship to” customer information and the end customer product or application into which the Company’s product will be incorporated. As data systems for capturing and tracking this data evolve and improve, the categorization of products by end market can vary over time. When this occurs, the Company reclassifies revenue by end market for prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each end market. The results below in the consumer end market are reflective of the sale of the Company's microphone product line in the fourth quarter of fiscal 2013.

Revenue Trends by Product Type

The following table summarizes revenue by product categories. The categorization of the Company’s products into broad categories is based on the characteristics of the individual products, the specification of the products and in some cases the specific uses that certain products have within applications. The categorization of products into categories is therefore subject to judgment in some cases and can vary over time. In instances where products move between product categories, the Company reclassifies the amounts in the product categories for all prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each product category. The results below in the other analog product category market are reflective of the sale of the Company's microphone product line in the fourth quarter of fiscal 2013.
