1. 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 the HSOP24 power package and DBS23P power package.
The amplifier operates over a wide supply voltage range from ±12.5 V to ±40 V and
consumes a low quiescent current.
2. Features
n Pin compatible with TDA8920B for both HSOP24 and DBS23P packages
n Symmetrical high operating supply voltage range from ±12.5 V to ±40 V
n Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied
Load (BTL) amplifier
n High output power at typical applications:
