DESCRIPTION/ORDERING INFORMATION

The TAS3308 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable 48-bit digital audio processor, 10:1 stereo analog input MUX, stereo ADC, six PWM output channels and other analog functionality. The TAS3308 is programmable with the graphical PurePath Studio™ & suite of DSP code development software. Purepath Studio is a highly intuitive, drag-and-drop development environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3308’s digital audio processing core.

TAS3308 processing capability includes speaker equalization and cross over, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms.

The TAS3308 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations.

A stereo 100 dB DNR ADC and six 105 dB DNR PWM output channels ensure that high quality audio is maintained through the whole signal chain. The PWM outputs utilize TI’s PurePath Digital PWM technology and seamlessly interface with TI’s extensive line of PWM input class D audio amplifiers.
