642

DESCRIPTION:

The MSK 642(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 642(B) is a transimpedance

amplifier capable of achieving a ±25V output voltage swing with an input current of ±9.3mA. 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 642

to drive 10nS pixels with ease and make it ideally suited for monitors with 1280 x 1024 or higher display resolutions.

The MSK 642 is mounted in a space efficient 9 pin single in-line bathtub package with heat sink fins.
