ADA4431-1YCPZ-R7

ADA4431-1YCPZ-R7 is an ultralow power SD video filter with load detection. It is a fully integrated video reconstruction filter that combines excellent video specifications with low power consumption, making it ideal for portable video filtering applications. It is able to detect whether a video load is present at the output, powering down the device when the load is disconnected. It operates on single supplies as low as 2.5V while providing the dynamic range required by the most demanding video systems. The on-board charge pump provides a virtual negative supply, allowing the video signal to be dc-coupled and the black level to be set to ground, while the sync passes cleanly at 300mV below ground. It is used in applications such as portable media players, portable gaming consoles, cell phones, digital still cameras, portable DVD players, portable video cameras.
