Cirrus Logic Analog Volume Control IC Delivers Superior Sound Quality for High-End Surround Sound, Pro Audio Systems.AUSTIN, Texas -- Eight-Channel Flagship CS3318 Delivers Unmatched Control Flexibility While Reducing System Cost Designers of high-end multichannel Using two or more paths for transmission or processing. It can refer to a variety of architectures including (1) multiple I/O channels between the CPU and peripheral devices, (2) multiple wires in a cable, (3) multiple "logical" channels within a single wire or fiber or (4) multiple audio systems have a new industry standard analog volume control integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for (IC): the CS3318 from Cirrus Logic (company) Cirrus Logic - A manufacturer of integrated circuits including the Advanced RISC Machine and display interface processors and cards for use as Windows accelerators (requiring dedicated driver software). http://cirrus.com/. , Inc.

With a superior dynamic range of 127 dB, 118 dB adjustable range and negligible distortion, the CS3318 delivers unmatched audio quality performance for high-end consumer and professional audio applications such as multichannel audio/video receivers, home theater An audio/video entertainment center that has a large-screen TV and hi-fi system with three speakers in the front (left, right and center) and left and right speakers in the rear. Starting in the early 1990s, video inputs were added to stereo receivers and preamplifiers. systems, digital mixing consoles In professional audio, a Digital Mixing Console (DMC), is an electronic device for combining, routing, and changing the dynamics of digital audio samples. The digital audio samples are summed to produce a combined output. , outboard Not built in. Outboard devices are external to the main unit. Contrast with inboard.

"Unlike some digital volume control products that limit the dynamic range, the CS3318 is a digitally-controlled analog volume control IC that offers a much broader dynamic range, 127 dB, and inherently superior audio quality as a result," said Jason Rhode, vice president, Mixed-Signal Audio Products Division, Cirrus Logic. Supporting eight channels of audio, such as for 7.1 surround-sound entertainment systems, the CS3318 provides a single-chip solution designed to reduce the need for external components, reducing circuit board space and helping OEMs achieve more compact designs at lower costs. The CS3318 operates from a +/- 9 V power supply, with 118 dB adjustable range from +22 db to -96 dB, negligible distortion and interchannel isolation. Cirrus Logic also offers the CS3308 IC, a pin-compatible +/- 5 V version with a very high dynamic range of 123 dB. Both the CS3318 and CS3308 feature a .25 dB step size, which is improved from the industry standard of .5 dB, provides upgraded resolution to ensure considerably smoother, finer volume adjustment. Additionally, patent-pending technologies such as dynamic address assignment and simultaneous master volume controls across devices over a single serial control bus (eg. I2C/SPI) gives additional flexibility to designers and helps to simplify designs. Pricing and Availability The CS3318 and CS3308 are now available and are priced at $9.22 and $6.97, respectively, in quantities of 10,000. Cirrus Logic Inc. Cirrus Logic develops high-precision analog and mixed-signal integrated circuits A mixed-signal integrated circuit combines analog circuits with digital signal processing (DSP) circuits on a single semiconductor die. An integrated circuit that includes both analog and digital circuitry (but no DSP), like a 555 timer, is generally not considered a mixed-signal for a broad range of consumer and industrial markets. Building on its diverse analog mixed-signal patent portfolio, Cirrus Logic delivers highly optimized products for consumer and commercial audio, automotive entertainment and industrial applications. The company operates from headquarters in Austin, Texas, with offices in Colorado, Europe, Japan and Asia. Cirrus Logic and Cirrus are trademarks of Cirrus Logic Inc.
