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 solution s.
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 manufact uring and RFI shield ing.
