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(1)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.
