The MSK 690 is a high voltage differential ampifier designed for use in CRT displays. With the high voltage power supply set to +65 volts, the output voltage of the MSK 690 can swing from +5 volts to +60 volts at a rate of 2000 v/S. The MSK 690 boasts a 30 MHz typical -3dB bandwidth and 20nS typical transition time making it a good candidate for high speed systems. The circuit is packaged in a space efficient, hermetically sealed 8 pin TO-3 to achieve good thermal efficiency and low cost. No isolation washer is necessary when heat sinking this device. The MSK 690 is available in both industrial and military grades.
