NXP Semiconductors TDA8927
The TDA8927 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: • TDA8927J/ST/TH; a digital power stage in a DBS17P, RDBS17P or HSOP24 power package • TDA8929T; the analog controller chip in a SO24 package. With this chip set a compact 2 × 80 W audio amplifier system can be built, operating with high efficiency and very low dissipation.FEATURES
