DESCRIPTION

The CVA2422TL contains three cascode video driver ampli fiers
without a common e mitte r. This device is de si gned f or ease of
use, adjustable gain, controlled EMI, OSD, and external peaking.

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.
