General description

The TDA8920 is a high efficiency class-D audio power amplifier. Typical output power is 2 x 80 W and it operates with

high efficiency and very low dissipation. The device comes in a HSOP24 power package with a small internal heatsink.

Depending on 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 up to =+30 V and consumes a very low quiescent current.
