TDA8920C
2 × 110 W class-D power amplifier
Rev. 02 — 11 June 2009 Product data sheet 1. 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 features low
quiescent current consumption. 2. Features
