APPLICATIONS
CRT driver for up to 89kHz monitors with resolution up
to 1280 x 1024.
Excellent Gray Scale Linearity
Emitter Peaking Option
Adjustable Gain
DESCRIPTION
The CVA2401T 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 gain for ease of use This device can drive monitors
with resolutions of 1280 x 1024 (non-interlaced) with pixel
frequency of 210MHz.
The part is housed in the industry standard 11-lead TO-220
molded power package. The heat sink is grounded.
