TECHNICAL INFORMATION
Stereo 10W (4) 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.
Applications
¾Computer/PC Multimedia
¾DVD Players
¾Cable Set-Top Products
¾Televisions
¾Video CD Players
¾Battery Powered Systems
Benefits
¾Fully integrated solution with FETs
¾Easier to design-in than Class-D
¾Reduced system cost with no heat sink
¾Dramatically improves efficiency versus
Class-AB
¾Signal fidelity equal to high quality linear
amplifiers
¾High dynamic range compatible with digital
media such as CD, DVD, and Internet audio
Features
¾Class-T architecture
¾Single Supply Operation
¾“Audiophile” Quality Sound
