Cirrus Logicís New Audio D/A Converter Achieves Industryís Highest Dynamic Range - Brings Recording Studio Quality Sound to Consumers

29-Sep-00

Cirrus Logic Inc. (NASDAQ: CRUS), the worldwide market share leader in audio chips, introduced the CS43122, a new CrystalÆ digital-to-analog (D/A) converter that achieves the highest performance of any audio D/A converter on the market. The CS43122 leverages Cirrus Logicís analog design expertise in an integrated, single-chip D/A converter with 122dB dynamic range and transparent audio conversion that delivers unprecedented sound quality for high performance audio systems. Dynamic range is a key audio specification that measures the amount of noise that a converter introduces to a system, which directly impacts sound quality and audio performance. By minimizing the noise level to the lowest in the industry, the CS43122 achieves 122dB dynamic range and provides transparent digital-to-analog conversion for the ultimate listening experience. ""We have combined our analog expertise and broad portfolio of intellectual property to once again set the standard for D/A converter performance with the CS43122,"" said Jason Carlson, Vice President and General Manager of Cirrus Logicís Consumer Products Division. ""Consumers can look forward to a new level of performance in next generation audio products, as manufacturers can integrate the CS43122 to deliver professional, high-fidelity audio products with unprecedented sound quality."" Consumers will now be able to enjoy audio performance once confined to professional settings such as recording studios. The CS43122 preserves the essence of original audio recordings by delivering transparent digital-to-analog conversion. This ability to reproduce the ambience and atmosphere of a live performance is a characteristic that manufacturers strive to deliver in audio systems such as high-end DVD-Audio players (24-bit, 192kHz sample rates), A/V receivers, outboard converters, mixing consoles and effects processors. The CS43122 achieves the highest dynamic range of any audio D/A converter in the market (122dB) and THD+N of 0.0007 percent. The new chip is based on Cirrus Logicís patented multi-bit delta sigma modulator architecture, analog filter technology, and second generation dynamic element matching. Combined, these proprietary technologies allow the CS43122 to achieve a flat noise floor that remains constant regardless of input signal characteristics. The CS43122 is an integrated, single-chip solution that allows manufacturers to achieve the highest level of performance so they can provide innovative professional and high-fidelity audio products to consumers. The Crystal CS43122 is offered in a 28-pin SOIC package and is currently available, priced at $12.20 in OEM quantities. For more information about Cirrus Logic, visit www.cirrus.com.
