Two new digital-input audio amplifiers with advanced processing from TI enhance the listening experience
Bangalore (March 16, 2009)- Texas Instruments Incorporated (TI) recently extended its digital audio portfolio with two digital-input audio power amplifiers that combine 32 bits of advanced audio processing with 20 watts of stereo output power into a single device. The TAS5709 and TAS5710 support speaker equalization (EQ) and dual-band dynamic range control (DRC) and offer TI’s unique 3D and bass boost technology, which enhances the overall sound experience by widening the sound stage and improving bass response. The TAS5710 features TI’s closed-loop architecture, which produces a rich, natural sound and lowers system cost by relaxing power supply performance requirements in consumer audio products, including high-definition televisions (HDTVs), media docking stations, digital radios and sound bars. (For more information on these amplifiers, please see www.ti.com/tas5710-pr.)
“We see an increasing demand among our customers for digital amplifiers with audio processing. TI’s TAS5709 and TAS5710 devices, along with the existing portfolio of digital audio, are designed to cater to these requirements” said Apoorva Awasthy, Business Development Manager, Texas Instruments India.
Key features and benefits of the TAS5709 and TAS5710
- 20-W stereo output power into 8 ohms at 18 V provides ample power at high efficiencies from a common supply rail. Closed-loop architectures maximize design flexibility and sound quality
- Up to nine biquad filters per channel equalizes speaker performance and compensates for less than ideal enclosure acoustics
- Dual-band DRC with selectable threshold, attack and decay protects speakers from damage and stops “bass rattling” of the cabinet/enclosure
- Royalty-free 3D and bass boost support widens the sound stage and improves bass response
- Store up to three sets of biquad coefficients for optimum audio performance over varying audio input frequencies. Sample rate changes are automatically detected and the correct coefficients selected without user intervention
- • 2-channel I2S input provides a direct connection to the digital processor, which reduces bill of materials cost
