Tri path Technol og y, I nc. - Techni cal I nformati on www.DataSheet4U.com TDA2500 STEREO CLASS-T DIGITAL AUDIO AMPLIFIER DRIVER USING DIGITAL POWER PROCESSING (DPP T M ) TECHNOLOGY Prelimiary Information Revision 0.9 - May 2005 GENERAL DESCRIPTION The TDA2500 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 TDA2500 is driving low impedance loads for professional and highend consumer amplifiers. The feedback and voltage range of the TDA2500 can be configured externally unlike previous Tripath modules such as TA0104A. Thus, the TDA2500 is capable of emulating Tripath’s previous series of TA0102A, TA0103A, and TA0104A amplifier drivers with the addition of a small number of external components. APPLICATIONS FEATURES Pro-audio Amplifiers Distribution Amplifiers High-end 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 Ov...
