GENERAL DESCRIPTION
The TDA8925 is a switching power stage for a high
efficiency class-D audio power amplifier system.
With this power stage a compact 2
×
15 W self oscillating
digital amplifier system can be built, operating with high
efficiency and very low dissipation. No heatsink is
required. The system operates over a wide supply voltage
range from
±
7.5 V up to
±
30 V and consumes a very low
quiescent current.
