Definition Video Filter Driver
TYPICAL APPLICATION DIAGRAM
The following schematic in Figure 2 is normally used for AC-coupled output and DC-coupled input with DAC which has
an output voltage range from 0V to 1.4V. AC-coupled output offers slightly lower power dissipation and high ESD
protection ability.
The schematic in Figure 1 is also popular in design.
