The following references are recommended: Also, the length of the signal traces from the preamplifier to the LM and from the LM to the CRT cathode should be as short as pos- sible. The IC is packaged in an industry standard 9-lead TO molded plastic power package.

dattasheet Note also that D14, D15, R29 and D13 are. V CC clamp diodes. Figure 6 shows the maximum power dissipation of the LM vs Frequency when all three channels of the device are driving an 8 pF load with a 40 V p-p alternating one pixel on, one pixel off signal. This example assumes a capacitive load of 8 pF and no re. Very important for arc protection. This minimizes parasitic capacitance in the. See Thermal Considerations section.
Tab is at GND. Increasing the value of L1 will speed up the circuit as well as increase overshoot. This graph gives the designer the information.
This corresponds to a speed degrada- tion of 0. Because of its high small signal bandwidth, the part may os- cillate in a monitor if feedback occurs around the video chan- nel through the chassis wiring.
The figure shows that the rise time of the LM increases. Figure 10 is the sche. LM vs Frequency when all three channels of the device. This is done to.
The schematic of the board is shown in Figure This resistor can be used to help control overshoot. The anode of protection diode D14 is con. Note also that D14, D15, R29 and D13 are placed to minimize the size of the video nodes that they are attached to.
The fall time shows a. To prevent this, leads to the. The diode placement and routing is very important for minimizing the voltage 5 www. The designer should note that if the load capacitance.

This demonstrates the importance of knowing the load capacitance in the application. The rise time shows a maximum variation relative to the cen. Referring to Figure 9there are three components R1, R2. The NSC demo board also. Note that the components are placed so that they almost line up from the output pin of the LM to the blue cathode pin of the CRT connector.
Figure 7 shows the variation in rise and fall times when the. MHz bandwidth then a maximum heat sink thermal resis. Figure 12 shows the. Increasing the values of R1.
