Technology
September, 2000
General Description
The TA2020-020 is a 20W continuous average two-channel Class-T Digital Audio Power
Amplifier IC using Tripath’s proprietary Digital Power Processing
technology. Class-T
amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D
amplifiers.
Applications
DVD Players
Mini/Micro Component Systems
Automotive Audio
Computer / PC Multimedia
Cable Set-Top Products
Televisions
Battery Powered Systems
Benefits
Fully integrated solution with FETs
Easier to design-in than Class-D
Reduced system cost with no heat sink
Dramatically improves efficiency versus
Class-AB
Signal fidelity equal to high quality linear
amplifiers
High dynamic range compatible with
digital media such as CD, DVD, and
internet audio
