General description

The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output
power is 2

×

 110 W with a speaker load impedance of 4

Ω

.

The TDA8920C is available in both HSOP24 and DBS23P power packages. The amplifier
operates over a wide supply voltage range from

±

12.5 V to

±

32.5 V and has a low

quiescent current consumption.
