The RA-2500 is a two-channel Amplifier Driver IC that uses Tripath's proprietary Digital Power Processing (DPP™) 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 RA-2500 is driving low impedance loads for professional and high-end consumer amplifiers. The feedback and voltage range of the RA-2500 can be configured externally. Thus, the RA-2500 is capable of emulating Tripath's series of TA0102A, TA0103A, TA0104A, and TA0105A amplifier drivers with the addition of a small number of external components.
