Technical Information - Preliminary
Revision 1.0 – December 2002
GENERAL DESCRIPTION
The TK2150 (TC2001/TP2150 chipset) is a two-channel, 200W (6
Ω
) per channel Amplifier
Driver that uses Tripath’s proprietary Digital Power Processing (DPP
TM
) 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
