TAS5622A Description
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 bined with the low idle loss and high power efficiency of...
