TDA8922BJ: 2 x 50 W class-D power amplifier ARCHIVED

Overview

Archived content is no longer updated and is made available for historical reference only.

The TDA8922B is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 x 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.
