Texas Instruments has announced a new addition to its line of high-performance digital audio processors. The new TAS3308 audio system-on-chip (SoC) is a single-chip solution that 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 device 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 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-resolution audio processing comes from a 48-bit data path that supplies the high level of precision required by advanced audio algorithms. Running at 135 MHz, the TAS3308 also includes an on-chip microcontroller that handles control and communications in order to optimise 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 105 dB DNR.
