The rail-to-rail output lets it swing the full video signal without headroom issues at 3.3 V single supply, which matters when the DAC reference is also 3.3 V and you cannot afford a clipping artifact on sync tips. ## Supply range and current budget Runs from a single 2.5 V to 3.6 V rail, drawing 4.7 mA typical supply current. No dual supplies needed — one clean 3.3 V rail and a 1 µF decoupling cap at the pin is the usual recipe. At 4.7 mA it is not a micropower part, but for a video filter in a camera module or set-top box that current is a rounding error in the total system budget. The exposed pad on the 16-UFQFN package needs a via stitch to the ground plane to keep the junction temperature in check if the ambient runs warm. ## Package and footprint reality The 16-LFCSP-UQ (3x3) package is a 0.5 mm pitch QFN-style land pattern. The exposed pad is the main thermal path and also the ground connection — the datasheet layout note (not reproduced here) calls for a 2x2 array of 0.3 mm vias under the pad. If your reflow profile is set for standard lead-free, the 3x3 mm body reflows cleanly; just watch the paste coverage on the center pad to avoid voids that lift the part during wave-solder. ## Lifecycle and compliance No PCN or obsolescence letter has been issued for this order code as of the current date. ## What the 7.9 MHz bandwidth means for your video path The 7.9 MHz -3dB bandwidth is the key selection parameter. Standard-definition video (PAL/NTSC) has a luminance bandwidth around 5-6 MHz; this filter passes that cleanly while rolling off above 7.9 MHz to suppress the DAC's sampling images. If you are feeding a 1080p HDMI encoder or a VGA DAC, the 7.9 MHz corner is too low — you would alias the higher-frequency content. But for CVBS, S-Video, or SD-SDI outputs this is the right pole. The single-pole roll-off shape means the stopband attenuation is modest; if you need sharper rejection at 27 MHz (the DAC clock), cascade a second-order passive LC after this stage.","metaTitle":"ADA4431-1YCPZ-R7 Video Reconstruction Filter, 7.9 MHz -3dB","metaDescription":"ADI ADA4431-1YCPZ-R7 single-channel video reconstruction filter, 7.9 MHz -3dB bandwidth, rail-to-rail output, 2.5V-3.6V supply, 16-LFCSP-UQ.

The ADA4432-1BCPZ-R7 is a 10.5 MHz bandwidth variant with single-ended output, and the ADA4433-1BCPZ-R7 is a 9.9 MHz differential-output version — both are in the same 16-LFCSP family but differ in bandwidth and output type.
