Philips TDA8950 ユーザーズマニュアル

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.
