TK2070
STEREO 70W (4) CLASS-T™ DIGITAL AUDIO AMPLIFIER
DRIVER USING DIGITAL POWER PROCESSING (DPP™)
TECHNOLOGY
Preliminary Information
Revision 2.1 – October 2003
GENERAL DESCRIPTION
The TK2070 (TC2001/TPS1035 chipset) is a bridged stereo 70W continuous average power per
channel, Class-T Digital Audio Power Amplifier using Tripath’s proprietary Digital Power ProcessingTM
technology. The TK2070 chipset consists of 1 TC2001 and 4 TPS1035’s to obtain a bridged stereo
configuration. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of
Class-D amplifiers.
