Texas Instruments Launches Audio Processor for Hi-Fi Consumer Audio

(Product News, 18 Mar 2008)

Texas Instruments Inc. (TI) has released a new addition to its line of high-performance digital audio processors—the new TAS3308 audio System on a Chip (SoC). The single-chip solution offers exceptional processing power for audio equipment manufacturers to create demanding applications such as digital television (DTV) audio subsystems, mini/micro component systems, 5.1 speaker bars and other consumer audio electronics.

The TAS3308 also integrates an analog multiplexer and stereo analog-to-digital converter (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 intuitive 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.

Texas Instruments' 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 TAS3308 audio SoC is a high-performance digital audio processor based on TI's industry-digital signal processing technology. The device's high-resolution audio processing comes from a 48-bit 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 microcontroller that handles control and communications in order to optimize system performance. Integrated analog functionality includes a stereo single-ended ADC with 100dB Dynamic Range (DNR), a 10 input analog multiplexer and six differential PWM outputs with 105dB DNR.
