The ADA4420-6 is a low cost video reconstruction filter specifically designed for consumer applications. It consists of six independent sixth-order Butterworth filters/buffers, three for standard definition (Y/C or CVBS) and three for high definition component signals (YPbPr or RGB).The ADA4420-6 operates from a single 5 V supply and has a low quiescent current of 32 mA, making it ideal for applications where power consumption is critical. A disable feature allows for further power conservation by reducing the supply current to less than 8 μA typical when the device is not in use.Each channel features a transparent sync tip clamp, allowing ac coupling of the inputs without requiring dc restoration.The output drivers on the ADA4420-6 have rail-to-rail output capabilities with 6 dB gain. A built-in offset of 250 mV allows the outputs to be dc-coupled, eliminating the need for large coupling capacitors. Each output is capable of driving two 75 Ω doubly terminated cables.The ADA4420-6 is available in a 16-lead QSOP and operates in the extended industrial temperature range of −40°C to +85°C.ApplicationsSet-top boxesDVD players and recordersHDTVsProjectorsPersonal video recorders

The ADA4431-1 is a fully integrated video reconstruction filter that combines excellent video specifications with low power consumption, making it ideal for portable video filtering applications. The ADA4431-1 is able to detect whether a video load is present at the output, powering down the device when the load is disconnected.The ADA4431-1 operates on single supplies as low as 2.5 V 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 300 mV below ground.When operating with the charge pump off, the ADA4431-1 provides a dc offset to keep the sync tip approximately 100 mV above ground. In addition, the part features SAG correction, which permits the use of smaller capacitors in applications with ac-coupled outputs.The ADA4431-1 is packaged in a low profile 16-lead LFCSP and operates in the industrial temperature range of −40°C to +85°C.APPLICATIONSPortable media playersPortable gaming consolesCell phonesDigital still camerasPortable DVD playersPortable video cameras
