The MAX9516 can detect the presence of a video load and report a change in load through the LOAD flag. This feature helps reduce overall system power consumption because the video encoder and the MAX9516 only need to be turned on when a video load is connected. If no load is connected, the MAX9516 is placed in an active-detect mode and only consumes 31W. Maxim's DirectDrive technology eliminates large outputcoupling capacitors and sets the output video black level near ground. DirectDrive requires an integrated charge pump and an internal linear regulator to create a clean negative power supply so that the amplifier can pull the sync below ground. The charge pump injects so little noise into the video output that the picture is visibly flawless.
