Very important for arc protection. It is very important to use induc.
Stock/Availability for: LM2439T
This board provides a good. The schematic of the board is shown in Figure Lm2493t example assumes a capacitive load of 8 pF and no re- sistive load. The IC is packaged in an industry standard 9-lead TO molded plastic power package. The following references are recommended: This corresponds to a speed degrada. Note also that D14, D15, R29 dztasheet D13 are.
LM vs Frequency when all three channels of the device. This graph gives the designer the information needed to determine the heat sink requirement for the appli- cation. The NSC demo board also. This demonstrates the importance. Used in conjunction with an LM, a complete video chan- nel from monitor input to CRT cathode l,2439t be achieved. Figure 12 shows the. Once the optimum values are determined the variable resistors can be replaced with fixed values.
V CC clamp diodes. The rise time shows a maximum variation relative to the cen.
It is very important to use induc- tors with datasheeg high self-resonant frequencies, preferably above MHz. The designer should note that if the load capacitance.
See Thermal Considerations section. Note also that D14, D15, R29 and D13 are placed to minimize the size of the video nodes that they are attached to. Figure 7 shows the variation in rise and fall times when the.
This minimizes parasitic capacitance in the. 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.
To prevent this, leads to the. Semiconductor Application Note Once the optimum values are determined. This is done to minimize the length of the video path between these two components.
Because of its high xatasheet signal bandwidth, the part may os.

Note that the components are placed so that they almost line up from the output pin of the LM to the blue cathode pin datashdet the CRT connector. Figure 8 shows the effect of increased load capacitance on.
The diode placement and routing is very important for minimizing the voltage 5 www. This demonstrates the importance of knowing the load capacitance in the application.

The anode of protection diode D14 is con- nected directly to a section of the the ground plane that has a short and direct path to the LM ground pins. Schematic and Connection Diagrams. To prevent this, leads to the video amplifier input circuit should be shielded, and input cir- cuit wiring should be spaced as far as possible from output circuit wiring. Also, the length of the.
This minimizes parasitic capacitance in the video path and also enhances the effectiveness of the pro- tection diodes. Note the location of the following components: This example assumes a capacitive load of 8 pF and no re. Figure 10 is the sche.
This corresponds to a speed degrada- tion of 0. Used in conjunction with an LM, a complete video chan. This resistor can be used to help control overshoot.
