Tripath Technology, Inc. - Technical Information
TA 2 0 2 4 C
STEREO 15W (4) CLASS-T™ DIGITAL AUDIO AMPLIFIER USING
DIGITAL POWER PROCESSING™ TECHNOLOGY
Preliminary Information
Revision 1.1 – September 2006
GENERAL DESCRIPTION
The TA2024C is a 15W/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.
The TA2024C has incorporated specific changes to improve the click and pop performance over
previous devices such as TA2024 and TA2024B. The TA2024C is recommended for all new designs
that previously used the TA2024 or TA2024B.
APPLICATIONS
Computer/PC Multimedia
DVD Players
Cable Set-Top Products
Televisions
Video CD Players
Battery Powered Systems
BENEFITS
Fully integrated solution with FETs
Easier to design-in than Class-D
Reduced system cost with no heat sink
Dramatically improves efficiency versus Class-
AB
Signal fidelity equal to high quality linear
amplifiers
High dynamic range compatible with digital
media such as CD, DVD, and Internet audio
