Overview

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.
