APPLICATIONS
CRT Driver for VGA and SVGA Color Monitors
DESCRIPTION
The CVA2415 contains three wide bandwidth, large signal
amplifiers designed specially to drive VGA and SVGA color
monitors. The device is a low cost CRT driver designed
especially to replace discrete solutions.
The part is housed in the industry standard 11-lead TO-220
molded power package. The heat sink is floating and may be
grounded for ease of manufacturing and RFI shielding.
