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.Applications
