The product is a 3-channel video filter for high-definition, progressive-scan, standard-definition, and bypass video, with an output buffer with +6dB gain, ideal for digital video disc (DVD) players, set-top box (STB) receivers, high-definition television (HDTV), digital video recorders (DVRs), and similar devices
The MAX11508/MAX11509 integrated video filters provide three selectable 6th‑order low‑pass channels for standard‑definition (SD), progressive‑scan (PS), high‑definition (HD) and bypass (BP) video. Each channel includes a transparent input clamp, optional bias circuitry for bipolar signals, and an output buffer with +6 dB gain that drives a 150 Ω video load.
These devices operate from a single +5 V supply, are offered in a lead‑free 14‑pin TSSOP package, and are intended for DVD players, set‑top boxes, HDTVs, DVRs and similar equipment. The datasheet includes electrical characteristics, pin descriptions, typical operating curves, PCB layout recommendations and ordering information.
| Output Buffer Gain | +6 dB |
|---|---|
| Supply Voltage Range | 4.75 V to 5.25 V |
| Shutdown Current | 1 pA (typ) |
They operate from a 5 V supply with a voltage range of 4.75 V to 5.25 V.
In shutdown mode the device current is reduced to about 1 pA (typ).
The integrated output buffer provides a gain of +6 dB, delivering a 2 Vp‑p signal into a 150 Ω load.
