TECHNOLOGY
Preliminary Information
Revision 0.9 – October 2005
GENERAL DESCRIPTION
The TDA2075A is a two-channel, amplifier driver, that uses Tripath’s proprietary Digital Power Processing
(DPP
TM
) technology. The TDA2075A 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 TDA2075A is typically configured as a split-supply, single-ended, stereo amplifier. The TDA2075A
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 TDA1400.
