TA0105A
STEREO CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER USING
DIGITAL POWER PROCESSING (DPP
T M
) TECHNOLOGY
Technical Information
Revision 2.2 – May 2005
GENERAL DESCRIPTION
The TA0105A is a two-channel Amplifier Driver IC that uses Tripath’s proprietary Digital Power
Processing (DPP
TM
) technology. Class-T amplifiers offer both the audio fidelity of Class-AB and the
power efficiency of Class-D amplifiers.
The typical application for the TA0105A is direct drive (no output transformer) in 70V and 100V
constant voltage amplifiers used for public address systems. The feedback and voltage range of
the TA0105A can be configured externally unlike previous Tripath modules such as TA0104A.
