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. The 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.
