2 x 80 W class-D audio amplifier

Leave a Comment
General Description:     
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. No heatsink is required, or depending on supply voltage and load, a very small one. The system operates over a wide supply voltage range from ±15 up to ±30 V and consumes a very low quiescent current.
