Typical Application

A typical application of the LM2418 is shown in

Figure 6

Used in conjunction with an LM1203 a complete video

channel from monitor input to CRT cathode is shown Per-

formance is satisfactory for all applications up to 640 by 480

lines Typical risefall times of this circuit are 15 ns with

this application feedback is local to the LM1203 an alterna-

tive scheme would feed back from the output of the LM2418

to the positive clamp inputs of the LM1203 This would pro-

vide better black level control of the system
