DESCRIPTION:
The MSK 643(B) is a wide bandwidth, high voltage color or monochrome CRT video amplifier designed specifically
to drive the grid of today's most demanding high resolution CRT monitors. The MSK 643(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 2.5nS enable the MSK 643
to drive 10nS pixels with ease and make it ideally suited for monitors with 1280 x 1024 or higher display resolutions.
The MSK 643 is mounted in a space efficient 9 pin single in-line bathtub package with two mounting tabs for direct
mounting to a heat sink or chassis.
