Technical Information
Revision 1.5 – September 2003
GENERAL DESCRIPTION
The TK2350 (TC2001/TP2350B chipset) is a two-channel, 300W (4Ω) 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
Audio/Video Amplifiers & Receivers
Pro-audio Amplifiers
Automobile Power Amplifiers
Subwoofer Amplifiers
Features
Class-T architecture
Pin compatible with Tripath TK2150
Proprietary Digital Power Processing technology
“Audiophile” Sound Quality
0.02% THD+N @ 50W, 8Ω
0.03% IHF-IM @ 30W, 8Ω
High Efficiency
95% @ 150W @ 8Ω
90% @ 275W @ 4Ω
Supports wide range of output power levels
Up to 300W/channel (4Ω), single-ended
outputs
Up to 1000W (4Ω), bridged outputs
Output over-current protection
