TA 0 1 0 5 A
STEREO CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER USING
DIGITAL POWER PROCESSING (DPPTM ) 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 (DPPTM) 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.
APPLICATIONS
Constant Voltage Amplifiers
Distribution Amplifiers
Pro-audio Amplifiers
BENEFITS
Reduced system cost with smaller/less
expensive power supply and heat sink
Signal fidelity equal to high quality Class-
AB amplifiers
No output transformer is needed due to
high supply voltage range
High dynamic range compatible with
digital media such as CD and DVD
FEATURES
Class-T architecture
Proprietary Digital Power Processing technology
High Supply Voltage Range
“Audiophile” Sound Quality
High Efficiency
Supports wide range of output power levels
Output over-current protection
Over- and under-voltage protection
38-pin Quad package
