HEAR THE DIFFERENCE WITH THE INDUSTRY'S FIRST CLOSED-LOOP, DIGITAL-INPUT CLASS-D AMPLIFIER FROM TI

Texas Instruments Incorporated has introduced the industry's first digital-input, 20-Watt stereo Class-D speaker amplifier with closed loop feedback. Closed loop architectures produce a richer, more accurate sound and lower system cost by relaxing power supply performance requirements. Highly flexible output configurations along with intuitive support tools ease design and speed time to market for manufacturers of HDTVs, including LCD, plasma and DLP® TVs, and media docking stations.

Innovative architecture improves sound quality, reduces power demands and lowers audio subsystem cost

Improving audio performance, the closed loop architecture enables the audio subsystem to have greater control over the speaker, reproducing a tighter, more accurate sound, with improved bass response. In addition, the closed loop architecture provides superior power supply rejection ratio (PSRR), which reduces power supply noise coupling into the audio band. Better noise immunity allows engineers to design lower-cost power supplies. In fact, for LCD-TVs, a TAS5706 audio amp can be powered off the existing +24V backlight power supply, making a dedicated power rail for the audio subsystem unnecessary.
