... LM2426. Thermal Considerations The package the LM2483 is in uses the ground pins ( 10, 11, and 12) to conduct heat from the LM2483. These pins should be connected to a ground plane that acts as a heat sink. See the example ground plane connected to these pins in the National Semiconductor PCB shown in Figure 7. > ...

... Typical Application A typical application of the LM2483 is shown in Figures 5 and Figure 6. Used in conjunction with an LM126X Preamp and an LM2426 CRT Driver, a complete video channel from input to CRT cathode can be achieved. Performance is ideal for HDTV applications. Figure 5 and Figure 6 are the schematic for the NSC demonstration board that can be used to evalu- ate the LM126X/LM2426/LM2483 ...
