DESCRIPTION
The CVA2422TL contains three cascode video driver amplifiers
without a common emitter. This device is designed for 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 manufacturing and RFI shielding.
