STEREO 15W (4Ω) CLASS-T™ DIGITAL AUDIO AMPLIFIER USING
DIGITAL POWER PROCESSING™ TECHNOLOGY
Preliminary Information
Revision 1.0 – January 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.
