Preliminary data sheet

1. 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.

2. Features
