●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 (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.
●FEATURES
