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.
