Overview
The TAS3208EVM PurePath Digital™ customer evaluation amplifier module demonstrates the DigitalAudio Processor TAS3208/TAS3208IA from Texas Instruments (TI).
TAS3208DCP/TAS3208IADCP is a fully programmable high-performance audio processor. It uses anefficient, custom, multi-instruction programming environment optimized for digital audio processingalgorithms. The TAS3208/TAS3208IA architecture provides high-quality audio processing by using a 48-bitdata path, 28-bit filter coefficients, and a single-cycle 28- ×48-bit multiplier with a 76-bit accumulator. Anembedded 8051 microprocessor provides algorithm and data control for the TAS3208/TAS3208IA. TheTAS3208 is the commercial version intended for home audio and other commercial applications.
This is a signal board EVM. The EVM is delivered together with two boards – an input board with SPDIF,ACD, and USB for PC control, and a output board with DACs and SPDIF transmitter. This system is acomplete 8-channel digital audio processor system that includes digital input/output (S/PDIF), analoginputs/outputs, interface to PC and DAP features, such as digital volume control, input and output mixers,auto mute, equalization, tone controls, loudness, dynamic range compression, and surround effects.
TAS3208 applications include digital televisions, home theater systems, mini-component audio systems,and pro audio.
