Cirrus Logic Releasese New D/A Converter

From Cirrus Logic’s press release:   Extending its industry-leading portfolio of analog semiconductor products, Cirrus Logic Inc. has introduced a new family of digital-to-analog (D/A)converters targeted for value-line entertainment systems in DVD-based markets and other entertainment markets, such as digital television, set-top boxes and automotive entertainment systems.

The new family of 10-pin D/A converters, the CS4344, CS4345, CS4346 and CS4348, give OEMs the industry’s smallest, most cost-effective 192 kHz stereo D/A converter while still retaining superior sound quality. This product introduction marks the 24th new analog product from Cirrus within the past 20 months.

“The CS434X family now gives Cirrus Logic the industry’s most comprehensive portfolio of stereo D/A converters for entertainment systems, including the smallest, most cost-effective 96 kHz and 192 kHz D/A converters,” said Jason Rhode, director of Analog Products Marketing, Cirrus Logic. “It complements and is compatible with our popular CS4334 family of D/A converters, giving designers a simple upgrade path.”

Helping reduce printed circuit board space requirements, the chips are offered in a low profile 10-pin package that is 50-percent smaller than Cirrus’ current eight-pin D/A converter family without sacrificing audio performance. Based on an advanced multi-bit Delta-Sigma architecture, the CS434X family delivers -95 dB THD+N and dynamic range of 105 dB. The CS434X D/A converters operate from a single +3.3 V or +5 V power supply and include value-added features such as patented automatic sample-rate detection, on-chip digital de-emphasis and Cirrus Logic’s Popguard technology to eliminate power cycling clicks and pops, which further reduces external components required. The CS4344, CS4345, CS4346 and CS4348 differ only in the serial audio interface format they support and are the ideal solutions for next-generation audio products that require a small, low-cost D/A converter with premium analog performance and sound quality.

Pricing and Availability

Each member of the CS434X family is available in a 10-pin, lead-free TSSOP package and is currently sampling to customers. In quantities of 10,000, each D/A converter is priced at $1.20.
