DESCRIPTION:
The MSK 641(B) is a wide bandwidth, high voltage color or monochrome CRT video amplifier designed specifically
to drive the cathode of today's most demanding high resolution CRT monitors. The MSK 641(B) is a transimpedance
amplifier capable of achieving a ±40V output voltage swing with an input current of ±10mA. The output of the
amplifier is DC biased at half the power supply voltage. Transition times in the range of 2nS enable the MSK 641 to
drive 10nS pixels with ease and make it ideally suited for monitors with 1280 x 1024 or higher display resolutions.
The 9 pin single in-line bathtub package is pin for pin compatible with the LH3424 and CR3424 and is a drop in
replacement for the high-rel versions of these devices with improved stability and thermal performance.
