150-W stereo, 300-W mono, 18- to 38-V supply, analog input Class-D audio amplifier

The TAS5613A is a high-performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD). It has the ability to drive up to 150 W.Achievable output power levels are dependent on the thermal configuration of the target application. A high performance thermal interface material between the package exposed heatslug and the heat sink should be used to achieve high output power levels Stereo into 4Ω speakers from a single 36V 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 only increases once the output levels move into clipping.

PurePath™ HD technology enables lower idle losses making the device even more efficient.
