TAS5261 provides OEMs with the industry's highest power single-chip digital amplifier power stage

The TAS5261 capable of driving more than 300 watts (W) into a 4-ohm speaker, while the two-channel TAS5162 digital amplifier power stage can drive 200 W per channel at 6 ohms and 125 W at 8 ohms. The devices enable higher efficiency and sound quality in a variety of audio applications, including many previously restricted from using digital amplifiers due to power requirements, such as high-end DVD receivers and mid- to high-end audio/video receivers

The TMS320C672x is the next generation of Texas Instruments' C67x generation

 The TMS320C672x includes the TMS320C6727B, TMS320C6726B, TMS320C6722B, and TMS320C6720 devices. Having a 32-bit architecture - that's a 24-bit mantissa and 8-bit exponent - means developers can capture more dynamic range of sound; Mixed precision instructions, enabling 16-bit by 32-bit operations, further improve processing efficiency.
