TDA8920B
2 100 W class-D power amplifier
Rev. 02 -- 07 November 2005 Product data sheet

1. General description
The TDA8920B is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 100 W. The device is available in the HSOP24 power package and in the DBS23P through-hole power package. The amplifier operates over a wide supply voltage range from 12.5 V to 30 V ( 32 V non operating) and consumes a very low quiescent current.
