Texas Instruments Inc. has announced a new addition to its line of high-performance digital audio processors. The TAS3308 audio SoC is a single-chip solution that offers high processing power for audio equipment manufacturers to create demanding applications such as DTV audio subsystems, mini/micro component systems, 5.1 speaker bars and other consumer audio electronics.

The TAS3308 integrates an analog mux and stereo ADC along with a high-performance digital audio processor and six pulse width modulated (PWM) output channels. This high degree of hardware integration is complemented with the PurePath Studio software development environment to allow customers to bring products with advanced digital audio signal processing to market with minimal investment in both hardware and software development resources.

High performance chip
TI's new processor features a fully-integrated digital audio signal chain including PWM outputs, reducing system cost and complexity and allowing for the direct drive of class D power stages.

The core of the new device is a high-performance digital audio processor based on TI's DSP technology. Superior high-resolution audio processing comes from a 48bit data path that supplies the high level of precision required by advanced audio algorithms. Running at 135MHz, the TAS3308 processor also includes an on-chip MCU that handles control and communications to optimize system performance. Integrated analog functionality includes a stereo single ended ADC with 100dB Dynamic Range (DNR), a 10 input analog mux and six differential PWM outputs with 105dB DNR.

Time-saving development support

The flexibility and depth of software support for the TAS3308 speeds time to market, promotes customization and product differentiation, and allows developers to provide consumers with high quality audio at an affordable cost. The device is fully supported by a traditional DSP software development tool kit and by the PurePath Studio graphical development environment, a highly efficient drag-and-drop development environment that accelerates the creation of new audio products. Developers have full control of audio processing and can draw on an extensive portfolio of pre-programmed basic audio functions and advanced audio algorithms from TI and leading third parties.

The TAS3308 Audio System on a Chip is sampling now, with volume availability scheduled for Q1 08. The device is packaged in a 100-pin quad flatpack (QFP). Suggested retail pricing is $5.60 in quantities of 10,000.

TI is one of the exhibitors in the IIC-China 2008.
