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 6 Ω.
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.
