The TAS5612LA is a feature optimized class-D power amplifier based on the TAS5612A.
●The TAS5612LA 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 TAS5612LA leads to industry-leading levels of efficiency ensuring a super "green" system.
●The TAS5612LA 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 TAS5612LA makes the amplifier easy to use; and, using TIs reference schematics and PCB layouts leads to fast design in time. The TAS5612LA is available in the space-saving, surface-mount, 44-pin HTSSOP package.
