MAX9516

19-0995; Rev 0; 9/07 KIT ATION EVALU E L B A IL AVA 1.8V, Ultra-Low-Power, DirectDrive Video Filter Amplifier with Load Detect General Description Features o 1.8V or 2.5V Single-Supply Operation o Low Power Consumption (6mW Quiescent, 12mW Average) o Video Load Detect o Reconstruction Filter with 5.5MHz Passband o DirectDrive Sets Video Output Black Level Near Ground o DC-Coupled Input/Output o Transparent Input Sync-Tip Clamp MAX9516 www.datasheet4u.com Operating at 1.8V from a single power supply, the MAX9516 amplifies standard-definition video signals and only consumes 6mW quiescent power and 12mW average power. The MAX9516 leverages Maxim’s DirectDrive™ technology. Combining DirectDrive with the external positive 1.8V supply, the MAX9516 is able to drive a 2VP-P video signal into a 150Ω load. The MAX9516 has the ability to detect and report the presence of a video load and reduce power consumption when the load is not present. 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 31µW. 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 line...
