1/8/2004 - Helping consumer electronics manufacturers set a new quality standard for the home theater listening experience, Texas Instruments Incorporated (TI) (NYSE: TXN) introduced the industry´s highest-performance digital audio PWM processor with an integrated 48-bit digital audio processor. TI will demonstrate the new device, together with TI´s recently announced single-channel 100-watt digital audio amplifiers, in the TI booth (#9011) at the Consumer Electronics Show in Las Vegas, January 8 - 11, 2004.
The new 48-bit TAS5508 processor will enable consumer electronics manufacturers to develop high-power, cost-effective 5.1, 6.1 and 7.1 systems at 500, 600 or 700-watts (W), reducing size and cost for home theater systems and DVD receivers. The high-performance TAS5508 provides up to eight speaker channels and 48-bit processing for sound field enhancement, enriching the home theater experience. Using the TAS5508 processor together with TI's extensive line of power stages, manufacturers are able to develop affordable high-power audio systems that offer much higher sound quality in an ultra-slim form factor.
"Home theater-in-a-box manufacturers are now demanding excellent audio quality with higher power driven to more channels," said Will Strauss, founder and principal analyst, Forward Concepts. "One of the hottest markets in home theater right now is the 800-watt, 7.1 home theater system - this is the sweet spot and the focus for manufacturers in the coming years and manufacturers will find that TI's TAS5508 fits this spot like a glove."
Highest Performing Audio Processor
The TAS5508 audio processor provides a ready-to-use sound field engine that simplifies audio system design. The device operates in an eight-channel mode that supports 7.1 or 6.1 speakers, bringing home theater-in-a-box to a new level of sound quality that can even rival today´s more expensive high-end A/V receivers. In addition, the TAS5508 offers a six-channel mode, enabling cost-effective, low-profile DVD receivers with integrated amplifiers.
Preprogrammed algorithms include loudspeaker normalization, second-order tone control, triple slope dynamic range compression, auto mute and loudness curves. With its 48-bit internal data path, the TAS5508 doubles the signal processing accuracy of the best available competitive devices, providing lossless bass management and crossover, with greater than 100 dB dynamic range. Most importantly, the 48-bit processing of the TAS5508 provides the dynamic range required for the best bass processing available in the market today.
Advanced Digital Amplification
The new TAS5508 audio processor is complemented by TI´s power stage offerings, including the recently-announced TAS5121 digital audio amplifier, the first available device to provide complete digital amplification with an integrated MOSFET H-bridge, for a single 100W speaker channel. The TAS5508 processor and TAS5121 amplifier operate together as a seamless high-performance solution for exceptional sound quality in affordable consumer audio systems. For maximum design flexibility for the manufacturer, the devices also can operate independently.
TI´s PurePath DigitalTM Audio Technology
The TAS5508 and TAS5121 are based on TI´s PurePath Digital technology, which allows consumer electronics manufacturers to build completely digital, end-to-end audio products with cutting-edge sound reproduction and the most lifelike sound in a compact form factor. By reproducing movie soundtracks or music exactly the way the artist intended, PurePath Digital technology offers the best in high-end digital entertainment to the everyday consumer. PurePath Digital technology complements other TI digital and analog products that support audio applications, such as digital signal processors (DSPs), switch mode power management, headphone amplifiers, digital interface and audio data converters.
Availability, Packaging and Pricing
The TAS5508 digital audio processor is now available in volume. Packaged in a 64-pin TQFP, the device is priced at $6.30 each in quantities of one thousand or more.
