Description
This Digital Audio HEXFET
廬
is specifically designed for Class-D audio amplifier applications. This MosFET utilizes the latest
processing techniques to achieve low on-resistance per silicon area. Furthermore, Gate charge, body-diode reverse recovery
and internal Gate resistance are optimized to improve key Class-D audio amplifier performance factors such as efficiency, THD
and EMI. Additional features of this MosFET are 175擄C operating junction temperature and repetitive avalanche capability.
These features combine to make this MosFET a highly efficient, robust and reliable device for Class-D audio amplifier
applications.
