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
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
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.
