TAS5631数据手册开发板套件编程器的评估板-音频放大器规格书PDF

描述 Description

DESCRIPTION
The TAS5631B is a high-performance PWM input class-D amplifier with integrated closed-loop feedback technology (known as PurePath HD technology) with the ability to drive up to 300 W
stereo into 4-Ω to 8-Ω speakers from a single 50-V supply.
PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers.FEATURES
