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:
With this chip set a compact 2
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
current.
