General description
The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is 2×75 W with a speaker load impedance of 6Ω. The TDA8922C 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.

FEATUREs
Pin compatible with TDA8950/20C for both HSOP24 and DBS23P packages
Symmetrical operating supply voltage range from±12.5 V to±32.5 V
