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.

The TAS5622A device is a thermally enhanced version of the class-D power amplifier based on the TAS5612A using large MOSFETs for improved power efficiency and a novel gate drive scheme for reduced losses in idle and at low output signals leading to reduced heat sink size. The unique preclipping output signal can be used to control a class-G power supply. This combined with the low idle loss and high power efficiency of the TAS5622A leads to industry-leading levels of efficiency ensuring a super "green" system. The TAS5622A uses constant voltage gain. The internally matched gain resistors ensure a high Power Supply Rejection Ratio giving an output voltage only dependent on the audio input voltage and free from any power supply artifacts. The high integration of the TAS5622A makes the amplifier easy to use; and, using TI’s reference schematics and PCB layouts leads to fast design in time.
