MAX7440/MAX7441/MAX7442 6-Channel Integrated Video Reconstruction Filters
The MAX7440, MAX7441 and MAX7442 are six‑channel integrated video reconstruction filters designed to replace 30 or more discrete components in DAC video applications. They operate from a single +5 V supply and support both DC‑coupled input and AC‑ or DC‑coupled output, providing a flat passband for PAL, NTSC and SDTV video signals.
The datasheet includes absolute maximum ratings, electrical characteristics, pin descriptions, typical operating curves, and layout recommendations. It also lists the 14‑pin SO package dimensions and provides application notes for set‑top boxes, hard‑disk recorders, DVD players and other video equipment.
