SGM9346
6-Channel, 6th-Order
Video Filter Driver for SD/HD
TYPICAL APPLICATION DIAGRAM
The following circuit may be used for direct DC-coupled drive by DACs with an output voltage range from 0V to 1.4V. AC-coupled or
DC-coupled outputs may be used with AC-coupled outputs offering slightly lower power dissipation.
