TDA8920BTH HSOP-24 Class D power amp

2 × 100 W class-D power ampli?er

The TDA8920B is a high ef?ciency class-D audio power ampli?er with very low dissipation. The typical output power is 2 × 100W.The ampli?er operates over a wide supply voltage range from +/-12.5V to +/-30V (+/-32V non operating) and consumes a very low quiescent current.


Features
