Description

This 2.1 channel audio amplifier reference design incorporates the TAS5825M digital stereo amplifier for left and right channel audio and the TAS5720M digital mono amplifier for the subwoofer channel. The design operates from a single audio source interface and is scalable to 5.1, 7.1 and 9.1 channel configurations, ideal for soundbar applications.

Features
  • PVDD tracking and thermal fold-back protection
  • Smart Amp technology
  • Modular, scalable multi-channel solution based on digital audio TDM
  • Integrated self-protection (OCE, CB3C, OTW, OTE, UVLO, OVLO)
  • Integrated audio DSP with enhanced 96kHz processing supporting several advanced audio process flows
  • Operates in TDM mode (as well as I2S) for speaker scalability
