TI delivers high power, integrated Class-D audio amplifiers

Dallas, Tex.—Texas Instruments Inc. has introduced two Class-D audio amplifiers that advance the home entertainment experience.

Capable of driving 600 watts, TI says the TAS5630 and TAS5631 feature the highest stereo output power in the industry, more than twice that of the closest comparable devices. Based on the company'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 of the TAS5630 and TAS5631 include 300-W stereo or 600-W mono output power at greater than 88 percent efficiency, which eliminates transformers or large heat sinks, reducing bill of materials and total solution cost; 0.03 percent THD at 1 W into 4-ohm load (stereo), which provides low distortion at normal listening levels; and power levels equivalent to traditional discrete Class-D amplifiers with 70 percent fewer components to lower system failure rate, accelerate time-to-market and achieve higher manufacturing yield.

The TAS56xx family is available today, to support multiple design configurations. The 600-W TAS5630 and TAS5631 are available in analog-input and PWM-input configurations, respectively, in two package sizes. The PHD package is $5.45 and the DKD is $6.35 in 1000-unit quantities. The 300-W TAS5615 and TAS5616 are also available in analog-input and PWM-input configurations, respectively, priced at $4.45 for the PHD package and $5.35 for the DKD.
