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.
Unlike traditional class-D amplifiers, the distortion curve does not increase until the output levels move into clipping.
PurePath HD technology enables lower idle losses, making the device even more efficient.
新一代高性能、高解析度 D 類放大器 (類比輸入) 已正式推出
以低 THD+N 呈現真實的 Ultra-HD 音質<0.005% and a bandwidth of up to 100kHz for output levels up to 315W Stereo />600W 單聲道:TPA3255
