描述 Description

The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output power is 2 x 110 W with a speaker load impedance of 4 Ω.
The TDA8920C is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from +-12.5 V to +-32.5 V and features low quiescent current consumption.
