DC COUPLED OUTPUT
Due to the internal level shift, the OPA360 can also be DC-
coupled to a video load. As shown in Figure 15, this
eliminates the need for AC-coupling capacitors at the
output. This is especially important in portable video
applications where board space is restricted.
The DC-coupled output configuration also shows the best
video performance. As seen in Figure 16, there is no line
or field tilt—allowing use of the lowest power supply. In this
mode, the OPA360 will safely operate down to 2.5V with
no clipping of the signal.
The disadvantage with DC-coupled output is that it uses
somewhat higher supply current.
