TI delivers industry's highest power, integrated Class-D audio amplifiers

Based on TI’s advanced closed-loop architecture, the amplifiers integrate PurePath HD technology to achieve high-definition media playback and ultra-low distortion in next-generation AV and DVD receivers, Blu-ray home theater systems, home theater-in-a-box, mini/micro component systems and professional audio systems.

Key features and benefits of PurePath HD technology:
• Audio bandwidth exceeds 73 kHz to achieve high-definition media playback in applications such as in Blu-ray home theater systems.
• Low distortion across frequency delivers a rich, natural sound.
• High power supply noise rejection reduces bill of materials and lowers system cost by relaxing power supply requirements. Power supply reference designs are available to further simplify development.
• Analog and pulse-width modulation (PWM) input options in pin-compatible packages maximize design flexibility.

Key features and benefits of TAS5630 and TAS5631:
• 300-W stereo or 600-W mono output power at greater than 88 percent efficiency eliminates transformers or large heatsinks, reducing bill of materials and total solution cost.
• 0.03% THD at 1 W into 4-ohm load (stereo) provides ultra-low distortion at normal listening levels.
• Offers power levels equivalent to traditional discrete Class-D amplifiers with 70% fewer components to lower system failure rate, accelerate time-to-market and achieve higher manufacturing yield.
• Pin compatibility with the TAS5615 and TAS5616 150-W stereo amplifiers maximizes design reuse for lower power systems.
