Product Summary

The TDA8924TH is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 × 120 W. The TDA8924TH 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. The applications of the TDA8924TH include Television sets, Home-sound sets, Multimedia systems, All mains fed audio systems and Car audio (boosters).
