150W 立体声/300W 单声道 PurePath™ HD 数字输入功率级

The is a high performance digital input Class D amplifier with integrated closed loop feedback technology known as PurePath™ HD with the ability to drive up to 150W 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 4 to 8 Ω 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.
