TAA2008 STEREO 9W (8 ) CLASS-T DIGITAL AUDIO AMPLIFIER USING DIGITAL POWER PROCESSING TECHNOLOGY
TECHNICAL INFORMATION Revision 1.0 – May 2006
GENERAL DESCRIPTION
The TAA2008 is a 9W/ch continuous average two-channel Class-T Digital Audio Power Amplifier IC using Tripath’s proprietary Digital Power Processing technology. The TAA2008, in a QFN package, along with extremely high efficiency, allows for a very compact amplifier design. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
APPLICATIONS FEATURES
LCD TV’s LCD Monitors Plasma TV’s Computer/PC Multimedia Battery Powered Systems
BENEFITS
Fully integrated solution with FETs Compact packaging and board design Reduced system cost with no heat sink Dramatically improves efficiency versus ClassAB Signal fidelity equal to high quality linear amplifiers High dynamic range compatible with digital media such as CD, DVD, and Internet audio Capable of driving a wide range of load impedances
