R e v i s i o n 4 . 0 – J u l y 2 0 0 3

General Description

The TA2021B is a 25W (4Ω) continuous average per channel Class-T Digital Audio Power Amplifier IC

using 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.
