Stereo 300W (4
) Class-T Digital Audio Amplifier Driver
using Digital Power Processing
TM
Technology
PRELIMINARY – January 2001
General Description
The TA3020 is a two-channel, 300W (4
) per channel Amplifier Driver IC that uses Tripath’s
proprietary Digital Power Processing (DPP
) technology. Class-T amplifiers offer both the
audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
