General description
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
Ω
.
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.
