General Description The TDA8924 is a high efficiency class-D audio power  amplifier with very low dissipation. The typical output  power is 2 × 120 W. T he device comes in a HSOP24 power package with a  small internal heatsink. Depending on supply voltage and  load conditions a very small or even no external heatsink  is required. The amplifier operates over a wide supply  voltage range from ±12.5 V to ±30 V and consumes a very  low quiescent current. Circuit Diagram 2 × 120 W class-D power amplifier
