ADA4420-6 Low Cost 6-Channel HD/SD Video Filter

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 (YPrPb or RGB). The ADA4420-6 operates from a single 5 V supply and has a low quiescent cur.
