Tripath Technology, Inc. - Technical Information
TDA2075
STEREO 75W (8Ω) CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER
USING DIGITAL POWER PROCESSINGTM TECHNOLOGY
ADVANCED INFORMATION
Revision 2.1 – December 2004
GENERAL DESCRIPTION
The TDA2075 is a two-channel, 75W (8Ω) per channel Amplifier Driver that uses Tripath’s proprietary
Digital Power Processing (DPPTM) technology. The TDA2075 offers higher integration over previous
Tripath amplifiers driver chipsets while providing exceptional audio performance for real world
applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of
Class-D amplifiers.
Applications
Powered DVD Players
Audio/Video Amplifiers & Receivers
Multimedia Speakers
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
