NXP Semiconductors TDA8926
The TDA8926 is the switching power stage of a two-chip set for a high efficiency class-D audio power amplifier system. The system is split into two chips: • TDA8926J: a digital power stage in a DBS17P power package • TDA8929T: the analog controller chip in a SO24 package. With this chip set a compact 2 × 50 W audio amplifier system can be built, operating with high efficiency and very low dissipation.FEATURES
