TA 2 0 2 1 B
STEREO 25W (4Ω) CLASS-T™ DIGITAL AUDIO AMPLIFIER DRIVER
USING DIGITAL POWER PROCESSING (DPP™) TECHNOLOGY
Technical Information
Revision 4.0 – July 2003
General Description
The TA2021B is a 25W (4Ω) continuous average per channel Class-T Digital Audio Power Amplifier IC
using Tripath’s proprietary Digital Power Processing (DPPTM) technology. Class-T amplifiers offer both
the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
Applications
DVD Receivers
Mini/Micro Component Systems
Computer / PC Multimedia
Cable Set-Top Products
Televisions
Battery Powered Systems
Benefits
Fully integrated solution with internal FETs
Easier to design-in than Class-D
Dramatically improves efficiency versus Class-AB
amplifiers
Signal fidelity equal to high quality linear
amplifiers
High dynamic range compatible with digital media
such as CD and DVD, and internet audio
