Tri pat h Tec hnol og y, I nc. - Te c hni cal I nf orm a ti on 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 (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 FEATURES 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 ClassAB amplifiers No output transformer is needed due to high supply voltage range High dynamic range compatible with digital media such as CD and DVD C lass- T architec ture 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 http://www.DataSheet4U.com/ 1 TA0105A – RW/ Rev. 2.2/05.05 Tri pat h Tec hnol og y, I nc. - Te c hni...
