TECHNICAL INFORMATION
Stereo 10W (4Ω) Class-T™ Digital Audio Amplifier using
Digital Power Processing™ Technology
TA2024
February 27, 2001 – Preliminary Rev. 1.0
General Description
The TA2024 is a 10W/ch continuous average two-channel Class-T Digital Audio Power Amplifier
IC using Tripath’s proprietary Digital Power Processing™ technology. Class-T amplifiers offer
both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
