1. General description
The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output
power is 2 × 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.
2. Features
n Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages
n Symmetrical operating supply voltage range from ±12.5 V to ±32.5 V
