Stereo 250W (4) Class-T Digital Audio Amplifier Driver using
Digital Power Processing (DPPTM) Technology
Technical Information
Revision 3.3 - June 2000
GENERAL DESCRIPTION
The TA0103A is a 250W continuous average (4), two channel Amplifier Driver
Module which uses 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
Audio/Video
Amplifiers/Receivers
Pro-audio Amplifiers
Automobile Power Amplifiers
Subwoofer Amplifiers
Home/PC Speaker Systems
Benefits
Reduced system cost with smaller/less
expensive power supply and heat sink
Signal fidelity equal to high quality Class-
AB amplifiers
High dynamic range compatible with
digital media such as CD and DVD
Features
Class-T architecture
Proprietary Digital Power Processing
technology
Supports wide range of output power
levels
