| Market Reality | The TDA7294 is the amplifier IC of a generation of DIY and consumer audio: a Multiwatt-15 DMOS power stage good for 100W-class output, in every active speaker and hobby amp built since the 1990s - and consequently one of the most relabeled chips in audio. The permanent confusion is with its sibling: the TDA7293 shares the pinout in single-chip use but adds higher rail capability and master/slave parallel mode that the 7294 lacks, so relabeled 7294 dies sold as 7293 work fine on a single-chip board and fail in parallel builds. Supply is steady from ST and the honest market, and the buying decision is authenticity first, grade second. | The TDA7294 is the amplifier IC of a generation of DIY and consumer audio: a Multiwatt-15 DMOS power stage good for 100W-class output, in every active speaker and hobby amp built since the 1990s - and consequently one of the most relabeled chips in audio.
