General description The TDA8922B is a high efficiency class-D audio power amplifier with very low dissipation.
The typical output power is 2 × 50 W.
The device is available in the HSOP24 power package and in the DBS23P through-hole power package.
The amplifier operates over a wide supply voltage range from ±12.
5 V to ±30 V and consumes a very low quiescent current.
