APPLICATIONS
CRT Driver for 1280 x 1024 and 1024 x 768 Color
Monitors
DESCRIPTION
The CVA2419TX contains three wide bandwidth, large signal
amplifiers designed specially to drive high resolution color
monitors. This device will provide excellent drive capability for
the 1280 x 1024 and 1024 x 768 color monitor. The
CVA2419TX is a low cost CRT driver designed 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.
