AUSTIN, Texas – July 24, 2000 – Cirrus Logic Inc. (NASDAQ:CRUS), the world’s market leader in audio chips, today announced the industry’s lowest power Digital to Analog (D/A) Converter, the CS43L43 that integrates four chips into one 16-pin TSSOP. This highly integrated chip is also the industry’s smallest solution and offers the highest available audio quality for portable devices, all at one-fourth the power consumption of typical low voltage D/A converters.

The CS43L43 integrates the functions of four chips into one 16-pin package that consumes only 16mW of power. It outperforms other low power chips on the market by providing higher Dynamic Range (96dB), better Total Harmonic Distortion plus Noise (THD+N) and longer battery life for portable audio applications. The THD+N of the CS43L43 is -85dB, a full 20dB improvement over existing solutions. The D/A converter allows more than 200 hours of music playback.

Cirrus Logic is the only company to provide a single chip solution with all the capabilities typically found in four separate chips: a D/A Converter, an Audio Effects Digital Signal Processor, an Analog Volume Control and a Headphone Amplifier.

“By combining the functions of four chips into one with the lowest power consumption, Cirrus Logic enhances its position as the industry’s leading producer of audio chips,” said Jason Carlson, vice president and general manager for the Consumer Products Division of Cirrus Logic. “We have designed this chip to provide the longest battery life and best sound quality for portable devices in the marketplace today.”

According to Will Strauss, president of Forward Concepts, an independent market research firm based in Tempe, Arizona, Cirrus Logic is the leading supplier of audio chips worldwide and represents 20 percent of the Audio IC (Integrated Circuits) market.
