Tripath Technology, Inc. - Technical Information
TK2150
STEREO 200W (6) CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER
USING DIGITAL POWER PROCESSINGTM TECHNOLOGY
Technical Information - Preliminary
Revision 1.0 – December 2002
GENERAL DESCRIPTION
The TK2150 (TC2001/TP2150 chipset) is a two-channel, 200W (6) per channel Amplifier
Driver 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
Powered DVD Players
Audio/Video Amplifiers & Receivers
Automobile Power Amplifiers
Subwoofer Amplifiers
Pro-audio 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
Pin compatible with Tripath TK2350 Chipset
Proprietary Digital Power Processing technology
