TAS5615中文资料具有集成反馈的模拟输入 160W 立体声（总计 300W）D 类放大器数据手册TI规格书

描述 Description

The TAS5615 is a high-performance analog input class-D amplifier with integrated closed-loop feedback technology (known as PurePath™ HD technology). It has the ability to drive up to 160 W

stereo into 8- 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.

Ultralow 0.03% THD+N is flat across all frequencies, ensuring that the amplifier does not add uneven distortion characteristics, and helps maintain a natural sound.

The efficiency of this class-D amplifier is greater than 90%. Undervoltage protection, overtemperature, clipping, short-circuit and overcurrent protection are all integrated, safeguarding the device and speakers against fault conditions that could damage the system.

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 PurePath HD is a trademark of Texas Instruments.
