The TAS5630B device is a high-performance analog-input class-D amplifier with integrated closed-loop feedback technology (known as PurePath HD technology) with the ability to drive up to 300 W Achievable output power levels are dependent on the thermal configuration of the target application. A high-performance thermal interface material between the exposed package heat slug and the heat sink should be used to achieve high output power levels. 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. When coupled with TIs class-G power-supply reference design for TAS563x, industry-leading levels of efficiency can be achieved.
