CONNECTION DIAGRAM

DESCRIPTION

The CVA2400T contains three wideband amplifiers, designed
specifically to drive a CRT. It features no crossover distortion for
excellent gray scale linearity, external emitter peaking to
maximize the high frequency gain at cross hatch pattern and
adjustable ga in for ease of use . This device can drive monitors
with resolutions of 1280 x 1024 (non-interlaced) with pixel
frequency of 176MHz.

The part is housed in the industry standard 11-lead TO-220
molded power pack age. The heat sink is gr ounded.
