The ADA4411-3 is an integrated triple video filter and buffer with selectable cutoff frequencies and multiplexed inputs for RGB, HD/SD.
The ADA4411-3 integrates three adjustable sixth‑order video filters with selectable cutoff frequencies of 9 MHz, 18 MHz, and 36 MHz. It supports RGB, YPbPr, YUV, SD and HD video standards, provides 2:1 multiplexing on all inputs, and offers variable gain (×2 or ×4) and DC offset adjustment.
The device operates from a single 5 V supply (wide range +4.5 V to +5 V) in a 24‑lead QSOP package, delivering rail‑to‑rail output swings of up to 4.5 V p‑p. It features low quiescent power (≈55 mA) and a disable mode that reduces supply current to about 15 pA, making it suitable for power‑critical applications such as set‑top boxes, DVD players, HDTVs and projectors.
