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 (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 TDA2500 is driving low impedance loads for professional and high-
end 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.
