Description
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.
Features
