TAS5631BDKDR
300 -W立体声/ 600 -W单声道的PurePath HD数字输入功率级 300-W STEREO / 600-W MONO PurePath HD DIGITAL-INPUT POWER STAGE
DESCRIPON
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 1 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.
