TDA2125A
STEREO CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER USING
DIGITAL POWER PROCESSING^TM TECHNOLOGY
Preliminary Information
Revision 0.55 – August 2005
GENERAL DESCRIPTION
The TDA2125A is a two-channel, amplifier driver, that uses Tripath’s proprietary Digital Power Processing
(DPP^TM) technology. The TDA2125A offers higher integration over previous Tripath amplifiers driver
chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers
offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
The TDA2125A is typically configured as a split-supply, single-ended, stereo amplifier. The TDA2125A
can also be configured single-supply, single-ended, stereo amplifier, via external component choice. For
applications that require bridged output drive, please refer to the TDA2125A.
