Description

The TDA8922 is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 ×25 W.

The TDA8922 is available in the HSOP24 power package with a small internal heatsink and in the DBS23P through-hole power package. Depending on the supply voltage and load conditions, a very small or even no external heatsink is required. The amplifier operates over a wide supply voltage range from ±12.5 to ±30 V and consumes a very low quiescent current.
