Adjustable Gain
DESCRIPTION
The CVA2403T is a high input impedance wideband triple
amplifier. The device is specifically designed to drive a CRT
featuring a high speed buffer for easy matching to a pre-amplifier,
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 220MHz.
The part is housed in the industry standard 11-lead TO-220
molded power package. The heat sink is grounded.
