3 Description
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 ...
