DESCRIPTION:

The MSK 645 is an amplifier designed specifically to suit the needs of todays high resolution CRT display moni-

tors. With a typical bandwidth of 150 MHz and transition times typically under 3.0nS the MSK 645 can easily drive

monitors with resolutions of up to 1280 x 1024. The output can swing up to 70 Vpp and gain is internally set to

minimize external component count. The MSK 645(B) is available screened to MIL-PRF-38534 and comes in a space

efficient package that is electrically isolated from the internal circuitry and can be attached directly to a heat sink for

efficient thermal dissipation.
