TAS3103 DAP Texas Instruments has released a new family of high-performance digital audio processors (DAPs) it reckons packs more processing power into a tiny, 38-pin/43mm2 package than ever seen before.
Both compact and economical, these new DAPs will provide high quality audio processing to consumer electronics manufacturers with a 48bit, fixed-function audio digital signal processor, without the need for additional programming.
TI's new TAS3103 DAP, the initial product in the TAS31XX family of devices, is designed for high performance, exceptional integration and cost-efficiency.
The TAS3103 DAP condenses board space by reducing the number of stand-alone devices usually needed for advanced processing, while operating at 135MHz and providing 540MIPS in a low 38-pin count package.
TI will also implement a broad range of turnkey audio effects algorithms to work with the TAS3103, including those from such companies as BBE Sound, Cooper Bauck, QSound, Sensaura and SRS, saving OEMs development resources and valuable time to market.
Combining form and functionality, this innovative technology can enhance a variety of audio entertainment systems, including: mini/micro component systems, boom boxes, DVD players, audio-video receivers (AVRs), televisions, home theatres and automotive sound systems.
"With the introduction of this new family of digital audio processors, TI is demonstrating its leadership and commitment to enabling affordable, high-quality digital audio from the audio source to the speaker", said Niels Anderskouv, Digital Audio and Video director at TI.
"The high-performance TAS3103 DAP offers a tremendous amount of audio processing power in a cost effective and compact solution".
The TAS31XX product line has a variety of audio processing features to address a wide range of applications, including most home and automotive entertainment products.
Each DAP is powered by a true 48bit, fixed-function digital signal processor core, supporting input and output data with up to 32bit resolution.
This enables extremely high quality audio processing with little or no impact to the audio stream, even for professional systems.
The new DAPs eliminate the need to program complex audio effects algorithms, thus simplifying development for reduced costs and faster time to market.
In addition, due to its work with leading sound processing companies, TI is implementing additional audio effects technology that can be customised requiring no additional algorithm programming.
The following audio processing algorithms are available on TAS31XX devices: soft volume, bass and treble controls adjust sound without pops or clicks; static and dynamic loudness compensation enhances bass effects; parametric and graphic equalisation increases sound quality; dynamic range compression and expansion enables late night listening mode and increases apparent loudness; input and output channel mixing/scaling simplifies input/mode selection; programmable dither preserves audio quality; effects processing supports 3D effects, stereo spreading, surround sound and bass enhancements; and an integrated pool of delay memory enables sound effects and imaging.
With its flexible functionality, the TAS3103 supplies three channels of processing with the entire suite of processing algorithms mentioned above.
It also has multichannel input and output capability while supporting audio sampling rates up to 96kHz.
Another notable feature is that the TAS3103 has the ability to support up to 16 bands of independent equalisation per channel.
The TAS3103 has a total delay of 42ms at 48kHz and can be used in any of the channels for speaker image correction, 3D and surround sound.
A spectrum analyser is also integrated and can be configured for use as a five- or ten-band analyser or stereo VU meter.
TI provides high-performance, programmable DSP and analogue-based solutions for many audio segments.
TI offers the performance headroom and flexibility in a low power solution for designs including portable Internet audio players, A/V receivers, digital radios, home jukeboxes and home theatres in a box.
Samples of the TAS3103 DAP are available now with volume production expected in September 2002.
The device is packaged in a 38-pin thin small-scale outline (TSSOP) package.
Pricing is $2.50 each in quantities of 50,000.
