STEREO 150W (4) CLASS-T DIGITAL AUDIO AMPLIFIER
DRIVER USING DIGITAL POWER PROCESSING (DPPTM)
TECHNOLOGY
Technical Information
Revision 3.1 – June 2000
GENERAL DESCRIPTION
The TA0102A is a 150W 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
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
