CVA2419TX
TYPICAL APPLICATION
A typical application of the CVA2419TX is shown in Figure 4.
Used in conjunction with a CVA1203, a complete video
channel from monitor input to CRT cathode is shown. In this
application, feedback is local to the CVA1203. An alternative
scheme would be feedback from the output of the CVA2419 to
the positive clamp inputs of the CVA1203. This would provide
slightly better black level control of the system.
