TDA8950
2
150 W class-D power amplifier
Rev. 02 — 11 June 2009
The TDA8950 is a high-efficiency Class D audio power amplifier. The typical output power
is 2
150 W with a speaker load impedance of 4 .
The TDA8950 is available in both HSOP24 and DBS23P power packages. The amplifier
operates over a wide supply voltage range from 12.5 V to 40 V and features low
quiescent current consumption.
