Product Summary

The TDA8922BTH is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 × 50 W. The TDA8922BTH 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.
