TDA2125A is a digital audio amplifier driver chip launched by Tripath, which uses Tripath's proprietary digital power processing technology, and has high fidelity and high efficiency. TDA2125A is typically configured as a single-ended stereo amplifier, and also supports single-ended output. Applications include powered DVD players, mini-compo systems, audio/video amplifiers and receivers, multimedia speakers, etc.
The TDA2125A is a two‑channel amplifier driver that employs Tripath’s proprietary Digital Power Processing (DPP) technology, offering the audio fidelity of Class‑AB with the efficiency of Class‑D. It can be configured as a split‑supply or single‑supply single‑ended stereo amplifier, and also supports bridged output drive.
Typical applications include powered DVD players, mini‑compo systems, audio/video amplifiers and receivers, and multimedia speakers, providing high efficiency, wide output power range, and protection features such as over‑current, over‑/under‑voltage, and over‑temperature safeguards.
