STEREO 300W (4Ω) CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER
USING DIGITAL POWER PROCESSING (DPPTM ) TECHNOLOGY
Technical Information
Revision 3.0 – September 2003
GENERAL DESCRIPTION
The TA3020 is a two-channel, 300W (4Ω) per channel Amplifier Driver IC that 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
