The TAS5614LADDV is a mono PurePath? HD digital-input Power Stage for use with high-power sound bars and mini combo systems. The TAS5614LA uses 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 TAS5614LA leads to industry-leading levels of efficiency ensuring a super green system. The TAS5614LA 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 TAS5614LA makes the amplifier easy to use and using TI's reference schematics and PCB layouts leads to fast design in time.
