The TAS5624A device is a thermally-enhanced version of the class-D power amplifier based on the TAS5614A 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 TAS5624A leads to industry leading levels of efficiency ensuring a super system.
●The TAS5624A 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 TAS5624A makes the amplifier easy to use; and, using TI’s reference schematics and PCB layouts leads to fast design in time. The TAS5624A is available in the space-saving, surface-mount 44-pin HTSSOP package.
