Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The ASU removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year, with early adoption permitted. The Company adopted this ASU in the first quarter of fiscal year 2022, with no impact to the financial statements. In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321) - Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force). This ASU clarifies the interaction of the accounting for equity securities and investments accounted for under the equity method of accounting, and the accounting for certain forward contracts and purchased options. This ASU is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year, with early adoption permitted. The Company adopted this ASU in the first quarter of fiscal year 2022, with no material impact to the financial statements. In May 2020, the SEC adopted final rules that amend the financial statement requirements for significant business acquisitions and dispositions. Among other things, the rules modify the significance tests and improve the disclosure requirements for acquired or to be acquired businesses and related pro forma financial information, the periods those financial statements must cover, and the form and content of the pro forma financial information. The final rules were effective January 1, 2021. The Company has adopted the final rules and applied changes in conjunction with its recently-announced business acquisition described in Note 8 - Acquisition.
Fair Value of Financial Instruments	The Company has determined that the only material assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents and marketable securities portfolio. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). •Level 1 - Quoted prices in active markets for identical assets or liabilities. •Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. •Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s cash equivalents and marketable securities portfolio consist of money market funds, debt securities, non-U.S. government securities, U.S Treasury securities and securities of U.S. government-sponsored enterprises and are reflected on our consolidated condensed balance sheets under the headings cash and cash equivalents, marketable securities, and long-term marketable securities. The Company determines the fair value of its marketable securities portfolio by obtaining non-binding market prices from third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value.
Revenues	Disaggregation of revenue We disaggregate revenue from contracts with customers by product line and ship to location of the customer. During the fourth quarter of fiscal year 2021, we adjusted how we report product line revenue to better represent our business and strategic focus. Sales are designated in the product line categories of Audio and High-Performance Mixed-Signal. Performance obligations The Company's single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of either a single type of good or a series of goods that are substantially the same, have the same pattern of transfer to the customer, and are neither capable of being distinct nor separable from the other promised goods in the contract. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer's contract. The vast majority of the Company's contracts with customers have an original expected term length of one year or less. As allowed by Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers, the Company has not disclosed the value of any unsatisfied performance obligations related to these contracts. The Company’s products typically include a warranty period of one to three years. These warranties qualify as assurance-type warranties, as goods can be returned for product non-conformance and defect only. As such, these warranties are accounted for under ASC 460, Guarantees, and are not considered a separate performance obligation. Contract balances Payments are typically due within 30 to 60 days of invoicing and terms do not include significant financing components or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract assets or contract liabilities recorded on the consolidated condensed balance sheets. Transaction price The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rebates, rights of return, warranties, price protection and stock rotation. Rebates are granted as a customer account credit, based on agreed-upon sales thresholds. Rights of return and warranty costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings. The Company estimates all variable consideration at the most likely amount that it expects to be entitled to receive. The estimate is based on current and historical information, including recent sales activity and pricing, available to the Company. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria.
Segment Information	We determine our operating segments in accordance with FASB guidelines. Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker under these guidelines. The Company operates and tracks its results in one reportable segment, but reports revenue in two product lines, Audio and High-Performance Mixed-Signal. Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources, rather than detailed information at a product line level. Additionally, our product lines have similar characteristics and customers. They share support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines. Revenue by product line is disclosed in Note 10 - Revenues.
