Overview

The TPA3244 Dolby Atmos® Soundbar Reference Design combines Ultra-HD audio and high dynamic range to create room filling audio experience from a small form factor system. The design leverages TI's high-performance TPA3244 amplifier, PCM5252 high-performance DAC with processing, and an integrated SoC for decoding and rendering Dolby Atmos®. The soundbar reference board provides 10 DAC + amplifier channels using TI's integrated audio DSP for independent channel processing which includes digital active crossovers, DRCs, and biquads to support the 5.1.2 soundbar output configuration. The design uses the 66AK2G audio SoC for Dolby Atmos® decode and rendering.

Features
  • 5.1.2 Dolby Atmos Soundbar
  • 10 x Class-D Amplifier Channels from 5 x TPA3244 in BTL
  • Immersive 3-Dimmensional Ultra-HD Audio
  • DAC Integrated DSP Audio Prcoessing for Active Crossover, Equalization, and Bass Enhancement
  • Single-chip SoC Dolby Atmos Solution
  • Digital and Analog Subwoofer Outputs

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
