Wiring Schematic Diagram

2 x 25 W class-D power amplifier with TDA8922.

General descriptionShow

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

The device 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.
