FMS6346_08 Datasheet, PDF (8/10 Pages) Fairchild Semiconductor – Six Channel, 6th-Order SD/HD Video Filter Driver

Typical Application Diagram
The following circuit may be used for direct DC-coupled drive by DACs with an output voltage range of 0V to 1.4V.
AC-coupled or DC-coupled outputs may be used with AC-coupled outputs offering slightly lower power dissipation.
