Description

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