APPLICATIONS
CRT driver for 14" or 15" monitors with resolution up
to 1024 x 768
DESCRIPTION
The CVA1406T contains three high voltage amplifiers with swing
range of more than 90V
p-p
at 120V supply. It is ideal for DC
coupled applications, thus reducing the cost by eliminating DC
bias components. It can deliver 12ns video signal, suitable for
14" and 15" applications.
The product is housed in the industry standard 11 lead
TO-220 molded power package.
