APPLICATION
CRT Driver for up to 90khz Monitors with Resolution
upto 1600 x 1280 (Non-Interlaced).
DESCRIPTION
The CVA6627S contains three wideband amplifiers designed
specifically to drive high resolution CRTs. It features excellent
gray scale linearity and high load capacitance driving
capability. This device can drive monitors with resolution of
1600 x 1280 (non-interlaced) with pixel frequency of 300MHz.
The part is housed in 12L Ceramic package with heat sink
grounded.
