APPLICATIONS
CRT driver for up to 76kHz Monitors
Excellent Gray Scale Linearity
Emitter Peaking Option
Adjustable Gain
DESCRIPTION
The CVA2400A contains three wide band triple amplifiers,
specifically designed to drive a CRT. It features no crossover
distortion for excellent gray scale linearity, external emitter
peaking to maximize the high frequency gain at the cross hatch
pattern and an adjustable gain for ease of use. This device can
drive monitors with resolutions of 1280 X 1024 (interlaced) with
pixel frequencies of 176MHz.
The part is housed in the industry standard 11-lead TO-220
molded power package. The heat sink is grounded.
